The banality of evil: Adolf Eichmann, Vladimir Putin and Donald Trump

Monday 30 March 2026

The courtroom in Jerusalem in 1961 was not merely a place of legal reckoning; it was a theatre in which the moral vocabulary of the modern age was put on trial. When Hannah Arendt travelled to observe the proceedings against Adolf Eichmann, she did not find a monster in the conventional sense. She found instead a man of unsettling ordinariness—one who spoke in clichés, deferred to authority, and seemed incapable of genuine reflection upon the consequences of his actions. From this observation emerged her most controversial and enduring formulation: the “banality of evil”.

Arendt’s argument was not that evil is trivial, nor that its consequences are anything other than catastrophic. Rather she insisted that the perpetrators of immense crimes may be neither ideologically fanatical nor psychologically deranged but instead frighteningly normal—individuals who have surrendered their capacity for thought, judgement and moral responsibility. Eichmann, in her portrayal, was not a sadistic architect of genocide in the mould of a gothic villain; he was a bureaucrat who had ceased to think about what he was doing. His evil lay precisely in this absence.

This insight, deeply uncomfortable at the time and no less so now, resonates with renewed urgency in the twenty-first century. The violence that scars our contemporary world is often not accompanied by the theatrical rhetoric of hatred that characterised earlier totalitarian regimes. Instead, it is frequently mediated through administrative language, executive decision-making and the casual exercise of power by figures who appear to regard human suffering as an abstraction—an externality to be managed rather than a moral reality to be confronted.

In the case of Vladimir Putin, the machinery of war has been rendered into a system of routinised destruction. Cities are reduced to rubble, civilian infrastructure is methodically targeted, and entire populations are displaced—not through spontaneous eruptions of cruelty, but through deliberate, calculated policies implemented by layers of command. The language used to justify these acts—“special military operations”, “denazification”, “security guarantees”—serves to obscure their human cost. It is a lexicon of euphemism, one that distances both perpetrators and observers from the reality of suffering.

Yet Arendt’s framework invites us to look not only at the apex of power, but also at the vast networks of compliance that sustain such regimes. The pilots who release their payloads, the officials who draft orders, the propagandists who shape narratives—all participate, to varying degrees, in a system that depends upon the suspension of moral reflection. The banality of evil is not confined to a single individual; it is diffused across institutions and societies.

In a different register, but with unsettling parallels, the rhetoric and conduct of Donald Trump reveal another dimension of this phenomenon. Here the violence is often discursive rather than kinetic, yet no less corrosive in its effects. The casual denigration of opponents, the trivialisation of truth, and the reduction of complex human realities to slogans all contribute to an environment in which empathy is eroded and responsibility diminished.

When public discourse becomes saturated with falsehoods and provocations, the boundary between reality and fiction begins to dissolve. In such a climate, actions that would once have been recognised as unacceptable may come to be perceived as normal, even inevitable. The danger lies not only in what is said or done, but in the gradual habituation of audiences to a degraded moral landscape.

Arendt warned that the greatest evil in the world is not radical evil, but evil committed by nobodies—by individuals who refuse to be persons in the full sense, who abdicate their capacity for thinking. In the contemporary context this warning acquires a broader significance. It is not merely a question of leaders who act without reflection, but of societies that permit such leadership to flourish.

The technological and institutional frameworks of the twenty-first century amplify this risk. Decisions that affect millions may be taken at a distance, mediated by screens and systems that abstract away the human consequences. Algorithms determine targets; bureaucracies process outcomes; narratives are disseminated at scale. In such an environment the space for moral reflection can easily be crowded out by efficiency, expediency, or ideological conformity.

Yet Arendt’s work also contains an implicit call to resistance. If the banality of evil arises from a failure to think, then its antidote lies in the cultivation of thought—of critical reflection, of judgement, of the willingness to confront uncomfortable truths. This is not an abstract philosophical exercise but a practical necessity. It requires individuals to resist the allure of easy answers, to question the language of power, and to recognise the humanity of those who are rendered invisible by systems of domination.

In Ukraine, where the consequences of unthinking power are felt with particular immediacy, this imperative is not theoretical. It is lived daily, in the resilience of communities that refuse to accept the narratives imposed upon them, and in the efforts of those who document, analyse and bear witness to the realities of war. To think, in Arendt’s sense, is to insist upon the reality of human experience against the forces that would deny or diminish it.

The enduring relevance of Arendt’s observations lies in their refusal to comfort. They do not allow us to relegate evil to the realm of the exceptional or the pathological. Instead they confront us with the possibility that the greatest dangers arise not from extraordinary malice, but from ordinary indifference—from the quiet, pervasive failure to think.

In an age marked by the actions of figures such as Putin and Trump, this lesson is both sobering and urgent. The challenge is not only to oppose the manifestations of power that inflict harm, but to address the conditions that make such harm possible. It is to recognise that the line between thought and thoughtlessness, between responsibility and abdication, runs not only through the corridors of power but through each of us.

For if evil can indeed be banal, then so too can the choices that sustain or resist it.
