Character Overview
Thomas Wade is one of the most compelling morally ambiguous characters in the Three-Body series -- though calling him a "villain" is not entirely accurate. He is better described as an extreme pragmatist operating in moral gray zones, a man who understood the dark nature of the universe earlier and more deeply than anyone else.
Wade's defining quality is an almost instinctive sense of crisis. He did not need to derive the Dark Forest theory like Luo Ji, nor did he need long-term observation like Zhang Beihai to reach his conclusions. He seemed to inherently understand that in the universe, survival is the first priority, and any price is worth paying for it.
Throughout the Three-Body series, Wade stands as the antithesis of Cheng Xin. If Cheng Xin represents humanity's most beautiful moral ideals -- kindness, compassion, an unwillingness to cause harm -- then Wade represents humanity's coldest survival logic -- decisiveness, ruthlessness, a willingness to sacrifice anything. The conflict between them is not one of good versus evil, but a collision between two equally profound yet incompatible aspects of human nature.
Wade's presence runs through all of Death's End. From the cold strategist of the Staircase Program, to the losing candidate for the Swordholder position, to the controller of Star Ring Corporation, to the champion of lightspeed ship development, and finally to the martyr who honored his promise and laid down arms -- each of his appearances pushed the story into a new moral abyss, forcing readers into agonizing choices between reason and emotion, survival and dignity.

Life Story
CIA Career and Character Formation
Before joining the Planetary Defense Council, Thomas Wade was a senior CIA operative. His intelligence career shaped his cold, efficient operational style -- in the CIA's world, decisions had to be swift, execution had to be decisive, and moral considerations were often a luxury.
Wade's specific experiences at the CIA are not detailed in the original text, but his capabilities in subsequent events suggest he participated in high-risk covert operations. His deep understanding of how power operates, his precise grasp of human weaknesses, his instinctive response to crisis situations -- none of these could be learned from books. They were forged in real life-and-death contests.
The CIA also gave Wade a distinctive cognitive framework. In intelligence work, information is always incomplete, and decisions must always be made under uncertainty. An excellent intelligence officer must learn to make judgments with insufficient information and bear the consequences of potentially being wrong. This way of thinking stood in stark contrast to the scholarly approach -- academics pursue certainty and complete information, while Wade was accustomed to acting in chaos.
Wade's CIA background also gave him a distinctive worldview: he was accustomed to thinking from worst-case scenarios and to sacrificing individual interests for larger objectives. This way of thinking, when applied to cosmic-level threats, actually became an advantage. While others were still trying to comprehend the full scope of the Trisolaran crisis, Wade had instinctively entered "wartime mode" -- a state where all resources serve the goal of survival and all moral constraints yield to existential necessity.
Wade possessed a unique "dark charisma." He was neither tall nor handsome, yet he radiated an unsettling aura of power. His gaze was cold and piercing, as though it could see through any facade. He spoke concisely and forcefully, never wasting a word, every syllable precisely serving his purpose. In his presence, most people felt an instinctive discomfort -- not fear exactly, but the sensation of being seen through.
Leading the Staircase Program: Cold Rationality
Wade's landmark entrance into public affairs was his appointment as director of the Staircase Program. The program was humanity's bold attempt to send a spy to the Trisolaran fleet -- using sequential nuclear detonations to propel a miniature probe to near-light speed and deliver it to the Trisolaran armada.
The very conception of the Staircase Program embodied Wade's thinking style -- bold, risky, breaking all conventions. Under the technological conditions of the time, humanity could not even send a complete vehicle to the Trisolaran fleet, let alone a living person. But Wade saw a possibility everyone else had overlooked: if you cannot send a whole person, send the most critical part -- the brain.
During the Staircase Program's decision-making process, Wade displayed his signature coldness. When technical limitations showed that a complete human body could not be sent, Wade unhesitatingly proposed sending only a brain. This proposal sent chills through everyone present -- to most, removing a living person's brain and launching it into space seemed an act bordering on cruelty. But Wade did not see it that way. In his calculations, a brain weighed only about two percent of the human body, meaning the rocket could accelerate it to far greater speed than a complete body, dramatically increasing the probability of reaching the Trisolaran fleet.
Selecting Yun Tianming: A Precise Calculation of Human Nature
When selecting the Staircase Program candidate, Wade demonstrated his deep understanding of -- and cold exploitation of -- human nature. He identified the terminally ill Yun Tianming -- a dying man's brain had scientific value without imposing excessive moral costs.
The logic behind this selection was chilling. Wade needed a candidate who met the following criteria: first, near death (so that brain extraction would not constitute murder); second, lacking a strong social network (so there would be minimal attention and opposition); third, possessing some exploitable emotional bond (to ensure the candidate's "voluntary" cooperation). Yun Tianming perfectly fulfilled all these conditions -- terminally ill, socially isolated, and harboring a deep unrequited love for Cheng Xin.
Wade exploited the emotional connection between Cheng Xin and Yun Tianming. He had Cheng Xin persuade Yun Tianming to accept the plan, knowing full well that Cheng Xin's very existence was the reason Yun Tianming could not refuse. This was a precise manipulation of human nature -- Wade forced no one; he simply placed the right people in the right positions and let the weaknesses of human nature do the work automatically.
Yun Tianming "voluntarily" accepted the plan. But the true degree of this "voluntariness" merits deep reflection. A dying man, asked by the woman he secretly loved to do something she believed meaningful for humanity -- could he refuse? Wade understood this perfectly, which was precisely why he chose this approach.
Wade's most shocking statement during the Staircase Program was his famous line: "Send her out. Send her out. Shoot me." (In the original context, describing his willingness to sacrifice anything to achieve the mission's objectives.) This became the defining footnote to Wade's character: he was willing to pay any price for mission success, including his own life. This was no bluster -- as his subsequent actions proved, he truly never valued his own life above the mission.
Execution and Failure of the Staircase Program
The Staircase Program's technical approach was highly innovative. Using a pre-deployed array of nuclear bombs in space, the spacecraft was progressively accelerated as each bomb detonated in sequence behind it, with the resulting radiation pressure providing continuous thrust. This propulsion method was like a cosmic version of a multistage rocket, using nuclear weapons instead of conventional chemical fuel.
After Yun Tianming's brain was extracted and specially cryopreserved, it was loaded onto a miniature spacecraft. Once launched, the nuclear pulse propulsion system accelerated it to a significant fraction of light speed. However, the plan did not proceed entirely as expected -- the spacecraft deviated from its intended trajectory during transit through the bomb array.
From Wade's perspective, while the Staircase Program failed to achieve its original reconnaissance objective (Yun Tianming was intercepted by the Trisolaran fleet rather than successfully infiltrating it), in the long run this "failure" produced unexpectedly significant results -- Yun Tianming later transmitted critical intelligence about cosmic survival back to humanity through three fairy tales. Of course, this outcome exceeded Wade's planning, but the core logic of the Staircase Program -- getting a human being into the Trisolaran fleet -- was indeed accomplished.
The Swordholder Contest: Defeated by Human Nature
In Death's End, the conflict between Wade and Cheng Xin formed one of the story's core tensions. Both were candidates for the Swordholder position -- the person who would control the Dark Forest deterrence system.
The Swordholder role was essentially a "human dead-man's switch" -- the holder had to be capable of pressing the deterrence button the instant the Trisolaran world launched an attack, destroying both civilizations simultaneously. This role required not wisdom, not kindness, not leadership, but a pure, unshakable determination -- the willingness to end two worlds without hesitation when the moment demanded it.
From a capability standpoint, Wade was undoubtedly the more suitable Swordholder. His coldness, decisiveness, and at-any-cost personality were precisely the qualities the role required. Had Wade become Swordholder, the Trisolaran world would almost certainly never have risked an attack -- because no one would doubt that Wade would actually press the button.
But human society made the opposite choice. After enduring Luo Ji's near-half-century of iron-fisted deterrence, humanity yearned for a more "humane" Swordholder -- someone who could represent human kindness and civilization. Cheng Xin perfectly fulfilled this aspiration. She was beautiful, kind, and compassionate -- the embodiment of humanity's finest qualities.
Wade held an extremely pessimistic view of Cheng Xin's election as Swordholder. He knew that her kindness and compassion would prevent her from pressing the button that would destroy both worlds at the critical moment. He reportedly said privately that if Cheng Xin became Swordholder, the Trisolaran world would certainly attack -- because they too could see she would never press the button.
Events proved his judgment entirely correct -- when the Trisolaran world launched its attack, Cheng Xin failed to activate the deterrence system, causing humanity to lose its most important strategic leverage. After deterrence failed, the Trisolaran fleet seized control of Earth, and humanity was forced to relocate to concentrated living areas in Australia.
Wade's state of mind during this process is worth contemplating. He must have felt an indescribable anger and despair -- not anger at Cheng Xin personally, but despair at humanity's entire selection mechanism. At the critical moment of civilizational survival, humanity chose someone destined to fail to wield the most critical weapon. This choice was not one person's error but a structural defect in human society's entire value system.
Taking Over Star Ring Corporation: "Advance! Advance!! Advance by Any Means Necessary!!!"
During the chaotic period following the end of the Deterrence Era, Wade made the most important strategic decision of his life -- taking control of Star Ring Corporation and transforming it into the core institution for lightspeed ship development.
Star Ring Corporation was originally an enterprise under Cheng Xin's name, operating with the resources and reputation she had accumulated during her time as Swordholder. After Cheng Xin entered hibernation, Wade gained control of Star Ring through a certain arrangement -- on the condition that he promised Cheng Xin that when facing critical decisions, he would wake her to make the final call.
This promise was the greatest contradiction of Wade's life. He knew full well that Cheng Xin's decision-making tendencies would be diametrically opposed to his own, knew that letting Cheng Xin decide was tantamount to abandoning his plan, yet he made the promise anyway. This was likely because gaining control of Star Ring was the only viable path forward under the circumstances -- without accepting this condition, he would have nothing.
Wade devoted all his energy to developing lightspeed ships. He knew this was humanity's last chance for survival -- only with lightspeed capability could humanity escape the solar system that would soon be swept clean. During this period, Wade uttered his most iconic slogan: "Advance! Advance!! Advance by any means necessary!!!"
The escalating exclamation marks in this phrase were not rhetorical decoration but a direct expression of Wade's inner conviction. The first "Advance" was direction; the second "Advance" was acceleration; the third "Advance by any means necessary" was a deliberate breach of all moral constraints. Wade was not unaware that his actions were morally problematic -- he was fully aware. But in his value system, the weight of survival was infinitely greater than the weight of morality.
Pushing Curvature Drive Research
In pushing lightspeed ship development, Wade once again demonstrated his by-any-means-necessary approach. He established his own research base, recruited top scientists, and even prepared to use armed force against the Federation government's ban on lightspeed ship research.
His relentless pursuit of curvature drive technology led to critical scientific breakthroughs. Under Wade's leadership, Star Ring Corporation's scientists successfully verified the theoretical feasibility of curvature drive and began designing an engineering prototype. This was an epoch-making achievement -- it meant humanity had for the first time a real possibility of building lightspeed ships.
However, a key side effect of curvature drive became the focus of political controversy. Curvature drive ships would leave a "wake" during flight -- a trace of altered spacetime curvature -- detectable by other civilizations in the universe. The Federation government concluded that use of curvature drive would expose the solar system's location, inviting strikes from more powerful civilizations (the very core of the Dark Forest principle). Therefore, the Federation government ordered a ban on lightspeed ship research and demanded Wade surrender all research results.
Wade's response was to prepare armed resistance. He deployed military forces at Star Ring Corporation's research base, readying to confront the Federation government's enforcement units. This was an extremely dangerous decision -- Wade was effectively challenging the authority of a government with the force of a single corporation. But Wade did not care. In his calculations, if lightspeed ship research was terminated, humanity would permanently lose its chance to escape the solar system. Compared to that consequence, a small-scale armed conflict was nothing.
Honoring His Promise and Surrender: The Last Humanity
At the story's pivotal turning point, Wade faced a choice: resist the Federation government's ban by force and continue lightspeed ship development, or honor his promise to Cheng Xin -- to let her make the final decision at the critical moment.
Wade chose to wake Cheng Xin. This decision alone already determined the outcome -- Wade knew in his heart what Cheng Xin would choose. He still chose to wake her because he had made a promise, and he was a man who kept his promises.
To everyone's surprise, this man who had practiced extreme pragmatism his entire life chose to keep his promise at the most critical moment. He laid down his weapons and handed the decision to Cheng Xin. Cheng Xin had a brief communication with Wade's team. She asked Wade whether they should continue fighting. Wade's answer was curt and resolute -- but he did not try to persuade Cheng Xin; he merely stated his judgment. In the end, Cheng Xin chose to surrender, and lightspeed ship development was terminated.
Trial and Execution: Final Words
Wade was subsequently arrested by the Federation government and tried for treason (preparing armed resistance against government orders). The trial was a mere formality for Wade -- he neither defended himself nor begged for mercy. He faced the entire judicial process with near-indifference, as though everything were exactly as he had anticipated.
Wade was sentenced to death. As he walked to his execution, he spoke to Cheng Xin the words that would echo through the entire Three-Body series: "Lose your humanity, and you lose much. Lose your animality, and you lose everything."
This was Wade's final message to humanity and the ultimate distillation of his life's philosophy. In the most concise language, he pointed out to Cheng Xin -- and to all the humans who had chosen Cheng Xin -- the fatal error they had committed: humanity had surrendered its last chance for survival in order to preserve its sense of morality and civilized self-image.
Wade's death was peaceful. A man who had spent his life dealing in death faced his own without fear, without regret, without rage. The only thing he left behind was that sentence -- like a seed, slowly germinating in the final years of human civilization, reminding everyone who heard it: this is what you got wrong.
Wade's Legacy
After Wade's death, lightspeed ship research was completely halted. The Federation government destroyed most of Star Ring Corporation's research data and sealed away curvature drive technology. However, ironically, a handful of scientists from Wade's team preserved critical data and continued secret research. Eventually, a lightspeed ship was indeed built -- but only a very few people managed to board it and escape the solar system before it was flattened into two dimensions.
If Wade had not been forced to stop his research, if Cheng Xin had not chosen surrender, humanity might have had more time to perfect lightspeed ship technology, and more people might have escaped. This "what if" became one of the most painful hypotheticals in the entire series.
Wade's legacy extends beyond science and technology -- it is above all philosophical. His dying words became a maxim repeatedly cited in humanity's later reflections on its own fate. In the final moments before the solar system was flattened into two dimensions, as survivors reviewed every wrong decision humanity had made, Wade's name and his words must have been the heaviest footnote.
Analysis from Original Text
The Deeper Meaning of "Animality" Philosophy
Wade's final words -- "Lose your humanity, and you lose much. Lose your animality, and you lose everything" -- are among the most philosophically rich sentences in the Three-Body series. They touch on a fundamental question of survival ethics: in the extreme scenario of civilizational extinction, how should one weigh morality against survival?
The "animality" Wade speaks of is not simple violence or cruelty, but rather the most primal survival instinct -- the determination to survive at all costs when facing annihilation. He believed that human civilization's vulnerability in the universe stemmed precisely from moral ideals that had shackled this instinct.
The structure of this statement also merits analysis. "Lose your humanity, and you lose much" -- acknowledging the value of humanity, acknowledging that losing it is a genuine loss; "Lose your animality, and you lose everything" -- but pointing out that losing the survival instinct carries an even more fatal price. Wade was not a nihilist who denied the value of humanity; he was a man who had made a clear priority ordering between two kinds of value. He knew that he had sacrificed much "humanity" for the sake of "animality" -- he knew he had lost a great deal -- but he considered it the necessary price.
The Multiple Meanings of "Advance! Advance by Any Means Necessary"
Wade's other iconic phrase -- "Advance! Advance!! Advance by any means necessary!!!" -- likewise carries rich philosophical content.
"Advance" here is not merely a physical direction of movement but the direction of civilizational development. Wade believed humanity's only way out was technological breakthrough -- specifically, lightspeed flight technology. Stagnation meant death, retreat meant extinction. Only by continuously advancing, advancing at any cost, could humanity have a chance.
"By any means necessary" directly challenged the moral floor of civilized society. Wade was not unaware of what "by any means necessary" meant -- he knew it implied potential bloodshed, potential authoritarianism, potential moral degradation. But in his value system, these costs were negligible compared to civilizational extinction.
This phrase also contains an implicit critique of the moral idealism Cheng Xin represented. Cheng Xin's choices always involved "lines she would not cross" -- she was unwilling to save humanity at the cost of harming others. Wade's response was: before the dark laws of the universe, "having lines you won't cross" equals "being unable to do anything at all."
Wade and Cheng Xin: Two Aspects of Human Nature in Opposition
The relationship between Wade and Cheng Xin forms the deepest character contrast in the series. Cheng Xin represents what humanity most wishes to be -- kind, compassionate, possessing moral boundaries. Wade represents what the universe forces humanity to become -- cold, decisive, unconstrained by morality.
Through this contrast, Liu Cixin conveys a tragic insight: in the Dark Forest universe, humanity's most beautiful qualities are precisely its most fatal weaknesses. Every moral choice Cheng Xin made led to catastrophic consequences, while every cold judgment Wade made was later proven correct.
But Liu Cixin's brilliance lies in not simply portraying Wade as "the right person" and Cheng Xin as "the wrong person." While Cheng Xin's choices led to catastrophic outcomes, the values she represented -- kindness, compassion, respect for individual life -- were precisely what made human civilization worth preserving. If humanity completely abandoned these values to survive, would the surviving "humanity" still be the same humanity?
Wade may have recognized this paradox to some degree. This might explain why he ultimately chose to honor his promise to Cheng Xin -- because if he had used violence to overturn Cheng Xin's decision, what he would have saved would not be "human civilization" but merely a group of "survival machines" stripped of their humanity.
The Weight of a Promise
Wade's ultimate decision to honor his promise to Cheng Xin is one of the most surprising turns in the entire series. Why would a man who practiced extreme pragmatism his entire life choose, at the most critical moment, to uphold a seemingly foolish promise?
One interpretation is that while Wade was ruthless, he was not without principles. His promise represented his last line of humanity -- even though he believed Cheng Xin's decisions would doom humanity, he respected her right to choose. This respect for individual will was precisely what he meant by "lose your humanity, and you lose much." Wade had lost much of his humanity, but he had not lost it all -- keeping his word was the last piece he preserved.
Another interpretation is that Wade may have realized that if he imposed his will by force, even if he succeeded, the order built through violence would not represent the human future he wanted to preserve. A civilization that survived by betraying a promise would be fundamentally corrupted.
There is an even deeper reading: Wade's promise-keeping was itself a transcendence of "animality." Pure "animality" would not keep promises -- animality cares only about survival. But Wade kept his word, suggesting the humanity in him had never truly vanished. He had spent his whole life suppressing his humanity in service of survival, but at the final moment, humanity struck back against animality. This counterattack was beautiful, and it was fatal.
Wade and Zhang Beihai: A Comparison
Wade and Zhang Beihai are the two most comparable characters in the Three-Body series. Both saw through to the true nature of humanity's situation, both chose extreme means to advance their convictions, and both paid with their lives. But there are critical differences between them.
Zhang Beihai was a dissembler -- he hid his true thoughts for an entire lifetime, presenting himself as a "triumphalist." Wade was a plainspoken man -- he never concealed his thoughts or positions, confronting everyone with an almost brutal directness. Zhang Beihai's weapons were patience and time; Wade's were power and action.
The deeper difference lies in their "modes of failure." Zhang Beihai's plan succeeded at the technical level -- he did hijack a ship and escape the solar system -- but he was defeated by the dark laws of the cosmos (the Dark Battle). Wade's plan failed at the human level -- he was defeated by his own adherence to a promise and by Cheng Xin's moral choice. Zhang Beihai was defeated from without; Wade was defeated from within.
Science Background
Curvature Drive and Lightspeed Ships
The core technology of the lightspeed ships Wade championed was curvature drive. Physicist Miguel Alcubierre's 1994 Alcubierre metric demonstrated that within the framework of general relativity, by warping spacetime, superluminal travel is theoretically possible. The ship itself remains stationary in local space while the spacetime bubble it inhabits moves at any desired velocity.
The principle of curvature drive can be understood through a simple analogy: imagine a marble on a rubber sheet. If instead of moving the marble itself, you compress the rubber in front of it and stretch the rubber behind it, the marble will move forward with the deformation of the sheet. Curvature drive does something similar -- rather than pushing the ship through space, it warps the spacetime around the ship so that space itself "carries" the ship along.
In the novel, a critical side effect of curvature drive is that it leaves a wake -- a trail of altered spacetime curvature detectable by other civilizations. This is why the Federation government sought to ban lightspeed ship research: use of curvature drive would expose the solar system's location. The wake problem also foreshadowed the eventual fate of the solar system.
Black Domain Theory
Another key concept Wade championed was the "black domain" -- creating a region around the solar system where the speed of light was reduced below escape velocity, making the solar system a cosmic "safety declaration." This concept was based on the novel's premise that civilizations in the universe can locally modify physical constants, including the speed of light.
The logic of a black domain is: if a star system voluntarily reduces its own speed of light to the point where escape is impossible, this amounts to declaring to the universe "I can never threaten anyone," because the civilization within that system can never leave. This is a self-imprisonment style safety declaration -- trading freedom for security.
From a physics perspective, the concept of a black domain is analogous to an "artificial black hole event horizon." In a real black hole, the escape velocity at the event horizon exactly equals the speed of light, so no matter (including light) can escape from inside. The black domain operates on a similar principle -- by reducing the speed of light within a region below the gravitational escape velocity, the region becomes a "slow-light black hole." From outside, no light signal from within the black domain can propagate outward, making it appear as a "dark region" in the cosmos -- both self-protective (undetectable) and self-imprisoning (inescapable).
The importance of Wade's promotion of the black domain concept was that it provided an alternative survival strategy besides flight. If lightspeed ships represented a "flee" strategy, then the black domain represented a "hide" strategy. Both strategies could protect humanity from Dark Forest strikes, but the black domain required sacrificing the freedom to ever leave the solar system.
Nuclear Pulse Propulsion in the Staircase Program
The nuclear pulse propulsion used in the Staircase Program is a concept for accelerating spacecraft using the radiation pressure from sequential nuclear detonations in space. This idea originated from the 1958 Project Orion, which envisioned detonating nuclear bombs one by one behind a spacecraft, using the resulting plasma shockwaves for thrust. Although Project Orion was terminated by the 1963 Partial Nuclear Test Ban Treaty, the basic physics is sound. The novel's Staircase Program refined this concept, pre-deploying nuclear bombs in space and having the spacecraft accelerate progressively as it passed through the bomb array.
The Science of Brain Extraction and Preservation
The Staircase Program's core premise -- extracting a human brain and launching it into space -- rests on neurocryopreservation technology. The brain must be removed from the body while preserving the integrity of neural connections (the connectome), then cooled to cryogenic temperatures using vitrification techniques that prevent ice crystal formation. Current science has achieved preservation of small mammalian brains with synaptic-level structural integrity, but reviving a cryopreserved brain remains far beyond present capabilities. Wade's willingness to pursue this path despite the enormous uncertainties reflects his general approach: act on the best available option, no matter how imperfect, rather than waiting for a perfect solution that may never arrive.
The Deterrence System and Game Theory
The Swordholder position that Wade competed for is fundamentally a game-theoretic construct. The Dark Forest deterrence system operates as a deadlock -- mutually assured destruction on a cosmic scale. For deterrence to work, the threat must be credible: the Swordholder must genuinely be willing to press the button. In game theory terms, this is the problem of "commitment credibility" -- how do you convince your opponent that your threat is real? Wade understood intuitively that credibility required a personality capable of following through. His cold, calculating nature made him the ideal deterrent; Cheng Xin's warmth and compassion made her the worst possible choice. The Trisolaran civilization, with their transparent thought processes, could read human psychology better than humans read each other -- they knew Cheng Xin would not press the button, which is why they attacked.
Character Analysis
Thomas Wade is the most unsettling and most thought-provoking character in the Three-Body series. He forces readers to confront an uncomfortable question: if saving all of humanity requires abandoning the most precious parts of our human nature, is that trade worth making?
Wade's tragedy is that he was right -- right about nearly every judgment -- but he could never persuade those around him to accept his correct assessments. Humanity ultimately chose the moral idealism represented by Cheng Xin, and the price was civilizational destruction.
His final decision to honor his promise added a touch of human warmth to this cold character. Even someone as extremely pragmatic as Wade had some line he would not cross deep inside. That line came not from moral doctrine but from his last shred of dignity as a human being.
Wade is the character in the Three-Body series most deserving of "rehabilitation." If we view the trilogy as a tragedy of human civilization, then Wade was the Cassandra who identified the source of tragedy but whom no one heeded. He saw the disaster coming, he proposed a plan to avert it, he had even begun implementation -- but at the final moment, humanity chose the more "humane" path, and that path led to annihilation.
Wade's entire life can be summarized by his own two phrases: he spent his whole life "Advancing! Advancing!! Advancing by any means necessary!!!" But in the end, he chose "lose your humanity, lose much" rather than "lose your animality, lose everything." This final choice -- keeping faith rather than fighting for survival -- proved that he understood the hair-thin boundary between humanity and animality more deeply than anyone.
