The essence of totalitarian government, and perhaps the nature of every bureaucracy, is to make functionaries… — 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.

What stuck in the minds of these men who had become murderers was simply the notion of being involved in something historic, grandiose, unique ("a great task that occurs once in two thousand years"), which must therefore be difficult to bear. This was important, because the murderers were not sadists or killers by nature; on the contrary, a systematic effort was made to weed out all those who derived physical pleasure from what they did. The troops of the Einsatzgruppen had been drafted from the Armed S.S., a military unit with hardly more crimes in its record than any ordinary unit of the German Army, and their commanders had been chosen by Heydrich from the S.S. élite with academic degrees. Hence the problem was how to overcome not so much their conscience as the animal pity by which all normal men are affected in the presence of physical suffering. The trick used by Himmler — who apparently was rather strongly afflicted by these instinctive reactions himself — was very simple and probably very effective; it consisted in turning these instincts around, as it were, in directing them toward the self. So that instead of saying: What horrible things I did to people!, the murderers would be able to say: What horrible things I had to watch in the pursuance of my duties, how heavily the task weighed upon my shoulders!

The case of the conscience of Eichmann, which is admittedly complicated but is by no means unique, is scarcely comparable to the case of the German generals, one of whom, when asked at Nuremberg, "How was it possible that all of you honorable generals could continue to serve a murderer with such unquestioning loyalty?," replied that it was "not the task of a soldier to act as judge over his supreme commander. Let history do that or God in Heaven."
