It is neither easy nor agreeable to dredge this abyss of viciousness, and yet I think it must be done, because what could be perpetrated yesterday could be attempted again tomorrow, could overwhelm us and our children.

Primo LeviPerhaps one cannot, what is more one must not, understand what happened, because to understand [the Holocaust] is almost to justify...no normal human being will ever be able to identify with Hitler, Himmler, Goebbels, Eichmann, and endless others.

They are non-human words and deeds, really counter-human.
