From what I’ve seen sometimes… thankfully they’re not all like that

Even then Hitler wasn’t even an atheist

I thought he was though

Hitler was against religion, but he still believed in god. Some say he was into the occult and Theosophy. Mein Kampf has several references to "God", "the Creator", "Providence" and "the Lord." Definitely not an atheist. https://en.wikipedia.org/wiki/Religious_views_of_Adolf_Hitler

Yes, who led the crusades? Theists. Who tortured people to death just because they didnt believe in their religion? Theists. Who starts a war arguing over which version of the same religion is the best? Theists.

And they did much more than that of course

Aka Catholics. The Catholics back then were bad
