One somewhat obvious explanation for this phenomenon is that of assuagement of guilt by rejecting the oppressor population one came from identifying with the victims, and this explanation is floated by an expert on the psychology of the children of perpetrators. Interestingly, though, none of those interviewed, when asked for why they converted to Judaism, mention the Holocaust or Nazism, instead giving theological reasons:
"During my theological studies at university it became clear that I couldn't be a minister in the church," he says. "I concluded that Christianity was paganism. One of [its] most important dogmas is that God became man, and if God becomes man then man also can become God." He pauses. "Hitler became a kind of god."
I tell Bar-On they talk obsessively about the Trinity. But is incredulity really a reason for abandoning a religion with a three-in-one god for one that still believes bushes talk and that waves are parted by the will of God? "That is another way of saying what I have already told you," he says. "They want to join the community of the victim. They may have their own way of rationalising it."
