"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. Many Germans and many Nazis, probably an overwhelming majority of them, must have been tempted not to murder, not to rob, not to let their neighbors go off to their doom (for that the Jews were transported to their doom they knew, of course, even though many of them may not have known the gruesome details), and not to become accomplices in all these crimes by benefiting from them. But, God knows, they had learned how to resist temptation."
"Wherever Jews lived, there were recognized Jewish leaders, and this leadership, almost without
exception, cooperated in one way or another, for one reason or another, with the Nazis. The
whole truth was that if the Jewish people had really been unorganized and leaderless, there
would have been chaos and plenty of misery but the total number of victims would hardly have
been between four and a half and six million people."
