Tangential point but just to be clear, Ardent's book is a journalistic work not something that is proven or widely accepted. There are many who disagree with this idea that Einchman was just a simple person who took orders since there are several documented events where it's clear that he was a piece of shit nazi and fully embraced the role.

> In Eichmann Before Jerusalem (2014), the German historian Bettina Stangneth reveals another side to him besides the banal, seemingly apolitical man, who was just acting like any other ‘ordinary’ career-oriented bureaucrat. Drawing on audiotapes of interviews with Eichmann by the Nazi journalist William Sassen, Stangneth shows Eichmann as a self-avowed, aggressive Nazi ideologue strongly committed to Nazi beliefs, who showed no remorse or guilt for his role in the Final Solution – a radically evil Third Reich operative living inside the deceptively normal shell of a bland bureaucrat. Far from being ‘thoughtless’, Eichmann had plenty of thoughts – thoughts of genocide, carried out on behalf of his beloved Nazi Party. On the tapes, Eichmann admitted to a sort of Jekyll-and-Hyde dualism:

I, ‘[t]he cautious bureaucrat,’ that was me, yes indeed. But … this cautious bureaucrat was attended by a … a fanatical [Nazi] warrior, fighting for the freedom of my blood, which is my birthright… Arendt completely missed this radically evil side of Eichmann when she wrote 10 years after the trial that there was ‘no sign in him of firm ideological convictions or of specific evil motives’. This only underscores the banality – and falsity – of the banality-of-evil thesis. And though Arendt never said that Eichmann was just an innocent ‘cog’ in the Nazi bureaucracy, nor defended Eichmann as ‘just following orders’ – both common misunderstandings of her findings on Eichmann – her critics, including Wolfe and Lipstadt, remain unsatisfied.
