"When confronted with the task of killing the Jews of Europe, the SS chief adopted the attitude of "somebody has to do the dirty job". Hannah Arendt's book, Eichmann in Jerusalem, describes how Nazi executioners endured the horrible acts they performed. Most were well aware that they were doing things that brought humiliation, suffering and death to their victims. The way out of this predicament was that, instead of saying "What horrible things I did to people!" they would say "What horrible things I had to watch in the pursuance of my duties, how heavily the task weighed upon my shoulders!" In this way, they were able to turn around the logic of resisting temptation: the temptation to be resisted was pity and sympathy in the presence of human suffering, the temptation not to murder, torture and humiliate.

There was a further "ethical problem" for Himmler: how to make sure that the executioners, while performing these terrible acts, remained human and dignified. His answer was Krishna's message to Arjuna in the Bhagavad-Gita (Himmler always had in his pocket a leather-bound edition): act with inner distance; do not get fully involved".
