If [she] had come to prefer the company of odd ducks, it was possibly because they had no conception of oddity, or rather, they thought you were odd … - Hannah Arendt

Eichmann, much less intelligent and without any education to speak of, at least dimly realized that it was not an order but a law which had turned them all into criminals. The distinction between an order and the Führer's word was that the latter's validity was not limited in time and space, which is the outstanding characteristic of the former. This is also the true reason why the Führer's order for the Final Solution was followed by a huge shower of regulations and directives, all drafted by expert lawyers and legal advisors, not by mere administrators; this order, in contrast to ordinary orders, was treated as a law. Needless to add, the resulting legal paraphernalia, far from being a mere symptom of German pedantry and thoroughness, served most effectively to give the whole business its outward appearance of legality. And just as the law in civilized countries assumes that the voice of conscience tells everybody, "Thou shalt not kill," even though man's natural desires and inclinations may at times be murderous, so the law of Hitler's land demanded that the voice of conscience tell everybody: "Thou shalt kill," although the organizers of the massacres knew full well that murder is against the normal desires and inclinations of most people. Evil in the Third Reich had lost the quality by which most people recognize it — the quality of temptation.

Not knaves, fools.

The trouble with Eichmann was precisely that so many were like him, and that the many were neither perverted nor sadistic, that they were, and still are, terribly and terrifyingly normal. From the viewpoint of our legal institutions and of our moral standards of judgment, this normality was much more terrifying than all the atrocities put together, for it implied — as had been said at Nuremberg over and over again by the defendants and their counsels — that this new type of criminal, who is in actual fact hostis generis humani, commits his crimes under circumstances that make it well-nigh impossible for him to know or to feel that he is doing wrong.
