Off the top of my head, I have come to the conclusion before that a lot of people try to explain the Nazis behavior through this supposed belief in the occult. I'm sure there is legitimacy to this, but the fact is that Hitler YM"V was a practicing Catholic until the end and most of the Nazis were still practicing Christians. I think the Nazis behavior, as a nation, can be better explained if you understand the history of the Holy Roman Empire and the Constantinian Reforms which put core beliefs of Jew-Hatred in the minds of Christians of the time.
Naziism was the culmination at the end of that era and the new Jew-Hatred is manifest through collectivist-leftism and militant atheism, not Christianity.
