Vasily Grossman, a Ukrainian Jew himself, wrote this after WW II on Jewish Nazi sympathizers and collaborators:

The violence of a totalitarian State is so great as to be no longer a means to an end; it becomes an object of mystical worship and adoration. How else can one explain the way certain intelligent, thinking Jews declared the slaughter of the Jews to be necessary for the happiness of mankind? That in view of this they were ready to take their own children to be executed - ready to carry out the sacrifice once demanded of Abraham?
