Zamasu, a Kaioshin apprentice in Dragon Ball Super, is the most unsettling villain in his universe because he does not seek power out of ambition nor kill for pleasure: he kills on principle. He observes the cosmos from his divine post, sees the cruelty, the war and the pettiness of mortals, and reaches a conclusion that strikes him as irrefutable —if humans are the source of evil, evil will vanish when humans vanish—. From this the "Zero Mortals Plan" is born: to exterminate the entire species in order to found a "just" universe, clean, perfect. The most disturbing thing is not his plan, but his inner peace. Zamasu does not consider himself a perpetrator of genocide: he considers himself a bringer of justice. And that serene conviction, that capacity to order the death of billions without a crack of remorse, is exactly what criminology has learned to dissect under the name of moral disengagement.
// The theoryThe switches that turn off conscience
The psychologist Albert Bandura, father of social learning theory, devoted the final part of his work to an unsettling question: how do ordinary people —and not only monsters— manage to do atrocious harm and go on sleeping soundly? His answer is moral disengagement: a set of cognitive mechanisms that selectively deactivate ethical self-control, so that the person can transgress their own moral norms without feeling the guilt that ought to stop them. Bandura identified eight of those "switches," and Zamasu flips almost all of them. The first and most powerful is moral justification: the harm is reframed as a service to a higher cause. Zamasu does not kill out of hatred, he tells himself, but out of justice; he does not destroy, he purifies. To this is added euphemistic language, which sanitizes violence with aseptic, solemn vocabulary —"plan," "correction," "divine order"— until extermination sounds like an administrative project. And the most decisive of all: dehumanization, which strips the victim of their status as a person. To Zamasu, mortals are not lives, they are "sin with a shape," an error in the design of the universe. And against an error one does not commit a crime: one corrects it.
The word that shields the executioner
Bandura insisted that moral disengagement is not conscious hypocrisy: the subject truly believes what he says. Therein lies its danger. A killer who knows he is doing evil still retains a conscience he might run into; a killer convinced he is doing good has no possible brake, because each death confirms his mission. Zamasu's weapon is not his divine energy: it is his vocabulary. As long as he can call genocide "justice" and massacre "purification," the horror does not reach him, because the words stand between the act and its meaning. Real criminology has seen this mechanism again and again in the great crimes of the state: one does not speak of murdering, but of "processing," "relocating," "sanitizing." The euphemism is the executioner's anesthetic. Zamasu is the fantasy version of a terrible truth —that the greatest atrocities in history were rarely committed by people who believed themselves evil, but by people persuaded that they were instruments of good—.

// The subjectThe idealist who named himself judge of the universe
What makes Zamasu a textbook case is that his descent does not begin in evil, but in an authentic moral indignation. The suffering of the weak genuinely repels him; the impunity of the powerful strikes him as intolerable. At that starting point he resembles any sincere reformer. The fracture arrives with a logical leap that Bandura would describe as the pinnacle of disengagement: advantageous comparison and attribution of blame to the victim. Zamasu reasons that his genocide is preferable to the eternal drip of mortal cruelty —a lesser evil against the "true evil"— and that, besides, humans have earned their fate: if they are exterminated, it is because their own nature demands it. The victim ceases to be a victim and becomes the cause of their own condemnation. To this is added the displacement of responsibility: Zamasu does not act in his own name, but as the arm of an abstract divine order, a "will of heaven" that commands him to do what he already wished to do. The sum of all these filters produces a functional and untroubled perpetrator of genocide: someone capable of erasing entire realities and regarding it as one who disinfects a wound.
Zamasu
// The flawThe ideal does not redeem the crime
The flaw in this case is the temptation to confuse the purity of the motive with the legitimacy of the act. Zamasu seduces us dangerously because he starts from a premise we share —the world is unjust, the strong abuse the weak— and appears to carry it to its coherent conclusion. But moral disengagement does not explain Zamasu in order to excuse him: it explains him precisely to disarm that trap. Bandura never held that believing in one's own goodness exempts one from responsibility; on the contrary, he showed that this belief is the mechanism of the crime, not its mitigation. A noble ideal does not turn genocide into anything other than genocide. Justice that needs to erase its victims in order to exist is not justice: it is its alibi. To explain is not to excuse —understanding how a god convinced himself that killing was purifying does not return a single life, nor make any of his dead less dead—.
There is a second flaw, more subtle: the symmetrical temptation to dismiss Zamasu as a unique fanatic, an accident of fiction with no echo in the real. It is the opposite. Zamasu matters because his logic is not exotic, but everyday and recognizable: the same verbal architecture that shields his crusade —"we purify, they are the problem, heaven commands it"— has preceded perfectly human persecutions, cleansings and massacres. The character is fantastical; the mental circuit that sustains him is not. And that is the discomfort he leaves behind: that the speech of the righteous and that of the executioner are, often, the same speech uttered by someone who has refused to look at what their hands are doing.
Distrust the one who kills in the name of good
Zamasu teaches us to read a pattern that reappears off the screen: crime dressed in virtue. The criminology of moral disengagement trains us to be suspicious not of the villain who confesses to cruelty, but of the one who proclaims himself pure —the one who divides the world between those worthy of existing and those who are surplus, the one who replaces "to kill" with "to purify," the one who offloads his responsibility onto a cause that, conveniently, coincides with his desire—. Every time a political, religious or ideological project describes a human group as a disease, a plague or an error, the same switch that Zamasu flips is being thrown: the dehumanization that prepares the ground for the unthinkable to become reasonable. The lesson is not to fear gods, but to distrust the language that turns people into problems to be solved. Because before any real extermination, someone had to find the words that made it sound just.
Three key takeaways
- Zamasu embodies moral disengagement (Bandura): the cognitive mechanisms —moral justification, euphemistic language, dehumanization— that allow atrocities to be committed without feeling guilt. His "Zero Mortals Plan" is a genocide that he experiences as a sacred crusade.
- His weapon is not divine power, but vocabulary: as long as he can call the massacre "justice" and extermination "purification," the words stand between the act and its meaning, and the horror does not reach him.
- To explain is not to excuse. The ideal does not redeem the crime: a justice that needs to erase its victims in order to exist is only the executioner's alibi. Memory is for the exterminated, not for the god who believed himself pure.

¿Quién es Zamasu?
Zamasu es un villano de Dragon Ball Super, analizado en KRIMINIS con la lente de la criminología. He did not see himself as a killer, but as a surgeon of the universe.
¿Por qué Zamasu se convierte en villano?
Zamasu and moral disengagement (Bandura): how sublimated language —"justice," "purification"— turns genocide into a crusade. The trainee god who convinced himself that erasing humanity was a sacred act.
¿Qué teoría criminológica explica a Zamasu?
El caso de Zamasu se analiza desde la Desconexión moral. The theory of moral disengagement (Bandura) explains how people who believe themselves good commit atrocities without feeling guilt: they justify the harm as something noble, dress it in euphemisms, and dehumanize the victim until ceasing to exist seems reasonable. Zamasu, the Kaioshin apprentice of Dragon Ball Super, takes those mechanisms to a divine extreme: sickened by the evil of mortals, he conceives the "Zero Mortals Plan" —the total extermination of humanity— and calls it justice, purification, order. A perpetrator of genocide who sleeps soundly because he believes himself the arm of a sacred crusade.
