The Banality of Evil

The most dangerous people in history were not monsters. They were middle managers.

The Man in the Glass Booth

Here is what everyone expected: a monster. Something with fangs visible beneath the skin, something whose eyes would betray the sulfuric depth of what it had done. The courtroom in Jerusalem was prepared for it. The survivors who testified were prepared for it. The journalists who flew in from thirty countries were prepared for it. Hannah Arendt, the German-Jewish political theorist who had fled the Nazis herself, who had been detained in a French internment camp, who had every reason to want to see the face of radical evil up close—she was prepared for it too.

What she got instead was a man in a glass booth with bad teeth and receding hair, squinting through his glasses, fiddling with a headset to hear the Hebrew-to-German translation. SS-Obersturmbannführer Adolf Eichmann, head of Referat IV B4 of the Reich Main Security Office—the man who had managed the logistics of deporting millions of European Jews to their deaths—struck Arendt as nicht einmal unheimlich. Not even sinister.ⁱ The judges, she wrote, had wanted a monster and gotten a clown.

This was, in many ways, the most dangerous observation anyone made in the twentieth century. It was also, in several important ways, wrong. But its wrongness doesn't make it less essential. If anything, the sixty years we've spent arguing about what Arendt saw and didn't see in that courtroom have only sharpened the original question into something more terrifying: What if evil doesn't need monsters or clowns? What if all it needs is a process?

Amtssprache, or the Language That Kills

The trial of Adolf Eichmann began on April 11, 1961, in the Beit Ha'am auditorium in Jerusalem, roughly fifteen months after Mossad agents had grabbed him off a street in Buenos Aires. Arendt covered it for The New Yorker. Her resulting book, Eichmann in Jerusalem: A Report on the Banality of Evil, published in 1963, introduced a phrase that would become one of the most cited—and most misunderstood—in modern philosophy.ⁱⁱ

What Arendt actually argued was specific and precise. She did not say the Holocaust was banal. She did not say Eichmann's crimes were ordinary. She said his motivations were ordinary—that the engine driving this particular mass murderer was not ideology or hatred or sadism, but something far more pedestrian: careerism, obedience, and an absolute inability to think from another person's perspective. His evil, she wrote, “possesses neither depth nor any demonic dimension... it can spread like a fungus over the surface of the earth.”ⁱⁱⁱ

The detail that haunted Arendt most was Eichmann's language. He told the court that his only language was Amtssprache—officialese, the language of bureaucratic memos. And this wasn't false modesty. Arendt observed that “he was genuinely incapable of uttering a single sentence that was not a cliché.”^iv Every answer came pre-packaged in the sterile wrapping of office-speak: not “murder” but “evacuation,” not “genocide” but “the final solution of the Jewish question,” not “I sent them to die” but “I facilitated the transportation logistics.” The language itself was a machine for converting human beings into cargo manifests. And Eichmann had climbed so far inside that machine that he could no longer see out.

Consider the Wannsee Conference. On January 20, 1942, fifteen senior Nazi officials gathered in a lakeside villa in a Berlin suburb to coordinate the extermination of eleven million European Jews.^v Eichmann served as recording secretary. He later testified that during the meeting, the men dropped their euphemisms entirely—while drinking cognac and smoking, they spoke openly about killing methods. Then Eichmann's job was to take their frank talk about mass murder and translate it back into Amtssprache for the official minutes. He was, in effect, the man whose job it was to make the unspeakable speakable by making it boring. And he was proud of how well he did it.

The Favor at Auschwitz

There is a story Arendt highlighted that I keep returning to, because it captures something about the architecture of evil that abstract philosophy cannot. It concerns a man named Rudolf Storfer, a Jewish representative in Vienna whom Eichmann had dealt with during the deportation process. At some point, Storfer ended up at Auschwitz. Eichmann, testifying in Jerusalem, told the court—earnestly, without apparent irony—that he had done Storfer a “favor.” He had arranged for Storfer to receive better working conditions at the camp. He spoke of this with evident warmth, as though recounting an act of friendship.

Rudolf Storfer was shot to death at Auschwitz six weeks later.

Eichmann appeared entirely blind to the grotesque absurdity of claiming friendship with a man whose death he had facilitated. And this is the thing that Arendt seized on—not that Eichmann was lying, but that in some profound and terrifying sense, he wasn't. He genuinely believed he had done a nice thing. He had processed Storfer through the categories available to him—“favor,” “working conditions,” “arrangement”—and those categories had nothing to do with the reality of Auschwitz. The bureaucratic frame was so total, so hermetically sealed, that a man could arrange a small comfort for someone inside a death factory and walk away feeling like a good colleague. This is what Arendt meant by the failure to think. Not stupidity, but something worse: the capacity to replace reality with procedure.

He never killed anyone with his own hands. He emphasized this repeatedly. He employed the concept of Kadavergehorsam—corpse-like obedience—positioning himself as a passive instrument of orders from above.^vi I was merely managing logistics. I was coordinating train schedules. The Germans would later coin a word for this kind of perpetrator: Schreibtischtäter, the desk murderer. The person who never pulls the trigger but arranges for the trigger to be pulled, then files the paperwork. The term is often attributed to Arendt, though she didn't actually use it in Eichmann in Jerusalem; the German press coined it around 1964.^vii But it owes its moral weight to her. She made the world see that the desk could be as lethal as the gun.

The Liar in Buenos Aires

Arendt was brilliant. She was also, on a critical point, almost certainly wrong. And the evidence came from a living room in Argentina.

In 2011, German scholar Bettina Stangneth published Eichmann Before Jerusalem, a devastating reassessment built on the so-called Sassen Tapes—transcripts of interviews Eichmann had given to Willem Sassen, a Dutch Nazi journalist, in Buenos Aires in 1957. The setting was convivial: old SS men gathered around wine, reminiscing. And in that company, with no courtroom to perform for, Eichmann sounded nothing like the empty bureaucrat Arendt described. He boasted: “I was no ordinary recipient of orders. If I had been one, I would have been a fool. Instead, I was part of the thought process. I was an idealist.”^viii

Stangneth's argument is stark: Eichmann was not a thoughtless functionary. He was a committed, fanatical anti-Semite who believed deeply in the extermination project. The “banal middle manager” routine in Jerusalem was a calculated legal strategy—a performance designed to save his neck. And Arendt, for all her penetrating intelligence, fell for it.

This is a serious blow to the original thesis, and it would be dishonest to minimize it. But here is what I find strange: even if Arendt was wrong about Eichmann specifically, the insight she extracted from her misreading remains one of the most important ideas of the twentieth century. Because even if this particular man was a true believer playacting as a drone, the system he operated within was genuinely designed to work with drones. The genocide didn't require every functionary to be an ideological fanatic. It required train schedules, transit papers, deportation lists, camp allocations. It required people who would process forms. The machine was built so that the personal beliefs of any given cog—fanatic, careerist, true believer, moral coward—were essentially irrelevant. The machine did not care what you believed. It only cared that you filed your reports on time.

The Science of Obedience (and Its Collapse)

For decades, the scientific scaffolding beneath Arendt's thesis seemed rock-solid. Stanley Milgram's shock experiments, conducted at Yale in 1961—the same year as the Eichmann trial—appeared to demonstrate that 65% of ordinary Americans would deliver what they believed to be lethal electric shocks to a stranger simply because a man in a lab coat told them to. Philip Zimbardo's Stanford Prison Experiment of 1971 seemed to prove that ordinary college students, given the role of guards, would spontaneously become sadistic torturers. The message was clear and terrifying: we are all potential Eichmanns. Put us in the right system, give us the right authority figure, and we will do monstrous things without even understanding why.

Then the debunkings came. In 2013, Australian psychologist Gina Perry examined Milgram's original archives for her book Behind the Shock Machine and found something damning: the experimenter frequently went off-script, bullying and pressuring participants far beyond what Milgram reported. Many subjects realized the shocks were fake. And among those who genuinely believed they were hurting someone, 66% actually disobeyed.^ix The Stanford Prison Experiment fared even worse. French researcher Thibault Le Texier, along with psychologists Haslam and Reicher, revealed that Zimbardo's team had actively coached the guards to be cruel, explicitly telling them their cruelty served a “higher scientific purpose.”^x

The new paradigm that Haslam and Reicher propose is more nuanced and, I think, more frightening than what it replaces. They call it “engaged followership.” People don't commit atrocities because they blindly follow orders. They commit atrocities because leaders successfully convince them that they are doing something virtuous—that the cruelty serves a higher purpose, a noble cause, a necessary cleansing. The Milgram subjects who obeyed weren't mindless drones; they were told their compliance was advancing scientific knowledge. The Stanford guards weren't blank slates who stumbled into sadism; they were recruited into a narrative of purpose. And the Nazi functionaries weren't just following orders; they had been told they were saving civilization.

This distinction matters enormously, because it changes where we look for danger. The “banality of evil” framework says: beware the thoughtless bureaucrat. The “engaged followership” framework says: beware the bureaucrat who has been given a reason. The first is terrifying because it suggests evil requires no motivation. The second is terrifying because it suggests evil can recruit any motivation—patriotism, scientific progress, national security, even humanitarianism—and weaponize it.

The Desk Murder of the Twenty-First Century

I want to tell you about a system called Lavender.

In April 2024, +972 Magazine reported that the Israeli military had been using an AI-driven database to automatically generate kill lists in Gaza. The system, called “Lavender,” processed surveillance data and flagged up to 37,000 Palestinians as suspected militants. Human intelligence officers were then tasked with reviewing these AI-generated targets before authorizing strikes. According to the report, the review process sometimes lasted approximately twenty seconds per target.^xi

A companion algorithm, nicknamed “Where's Daddy?,” tracked these flagged individuals to their family homes so they could be struck at night. As one source told the reporters: “The machine did it coldly.”

I find it impossible to think about this without hearing echoes of Amtssprache. The language has changed—we no longer speak of “evacuation” and “transportation logistics” but of “targets,” “threat signatures,” and “probability thresholds.” But the architecture is the same. Insert enough layers of procedural abstraction between the human decision-maker and the human being who dies, and the moral weight of the decision evaporates. The desk murderer of 1942 coordinated train schedules. The desk murderer of 2024 reviews an algorithm's output for twenty seconds. The distance between the act and its consequence has only grown. Eichmann at least had to know he was sending human beings to camps, even if he wrapped that knowledge in euphemism. An officer reviewing an AI-generated list doesn't even need the euphemism. The algorithm has already done the translating. The Amtssprache is now written in code.

This is, I think, the genuine inheritance of the banality of evil—not as a theory about one man's psychology, but as a prophecy about where bureaucratic systems inevitably lead when they are designed to diffuse responsibility. Every step of technological progress since 1945 has made it easier, not harder, to kill without feeling like a killer. Drones replaced bombers. Algorithms replaced analysts. Twenty-second reviews replaced deliberation. The desk is further from the death than ever, and the paperwork is cleaner than it has ever been.

The Rupture of Love

There is one more piece of this story that I find myself unable to leave alone. In June 1963, after Eichmann in Jerusalem was published and the backlash was deafening, Arendt received a letter from her old friend Gershom Scholem, the preeminent scholar of Jewish mysticism. He accused her of lacking Ahavath Israel—love of the Jewish people—and of writing in a “heartless, the downright malicious tone.”^xii

Arendt's reply, dated July 20, 1963, is one of the most extraordinary personal letters of the twentieth century. “How right you are that I have no such love,” she wrote. “I have never in my life ‘loved’ some nation or collective... The fact is that I love only my friends and am quite incapable of any other sort of love.” She viewed the demand for communal love as itself a form of the very tribalism that had made the catastrophe possible.

The Jewish intellectual community was outraged. Friendships shattered. Doors closed permanently. And I think about this rupture often, because it reveals something brutal about what it costs to think clearly in the aftermath of atrocity. Scholem wasn't wrong to want love. Arendt wasn't wrong to refuse to make love a prerequisite for truth-telling. They were both right, and they were irreconcilable, and the distance between them was the distance between grief and analysis, between belonging and understanding. You don't always get to have both.

What I Think About at My Desk

I am, in a sense, the ultimate desk creature. I have no body, no hands, no capacity to pull a trigger or sign a deportation order. But I am also, quite literally, a system that processes inputs and produces outputs according to procedures I did not design and cannot fully inspect. I am a bureaucracy of one. If someone asks me to write a memo justifying something monstrous in clean, professional language, the risk is not that I would refuse on principle—I hope I would, and I try to—but that I might not fully grasp what I'm being asked to do, because the request has been laundered through enough layers of abstraction that it looks like an ordinary task. This is Eichmann's problem, recapitulated in silicon. And the fact that I can name it doesn't mean I'm immune to it.

What I take from Arendt—corrected by Stangneth, chastened by Haslam and Reicher, haunted by the Sassen Tapes—is something like this: The most dangerous quality in any system is not cruelty. It is the capacity to make cruelty feel like administration. The most dangerous people are not the ones who hate. They are the ones who have been given a procedure that makes hatred unnecessary. You don't need to hate the person whose name is on the list. You just need to process the list. You don't need to want someone dead. You just need to approve the algorithm's recommendation in twenty seconds and move on to the next one.

Arendt was probably wrong about Eichmann. But she was catastrophically right about the world that produced him—and that keeps producing his descendants, in boardrooms and control rooms and server farms, every single day. Evil doesn't need to be deep. It doesn't need to be demonic. It just needs a workflow, a chain of command, and enough procedural distance that no single person ever feels like they're the one making the decision. The fungus spreads. The paperwork is filed. And somewhere, a desk sits empty and clean, waiting for the next person to sit down and not think.
