Godwin's Law meets historical fiction.
Hitler lost his faith around age 16. His various crimes while dictator of Germany, especially killing priests and religious, caused him to be automatically excommunicated hundreds of times over.
Appears as tho Hitler was somewhat religious long after he turned 18...

I did just read a quote from Hitler as an adult and in charge where he stated he was a Catholic and always would be. I will try to find it and post it. Of course, I don't believe he was a believer in God in the least.
