I'm going to take issue with your simplification and classification of Hitler, and the wider Nazi ideology here because I think this is very important given some of the patterns we see repeating from the early 20th century. There was a lot of nuance to the public and politically expedient viewpoints that Hitler professed regarding religion throughout his life versus his private viewpoints which colored the ideological mechanisms of Nazism.

It is tacitly incorrect to state that Hitler was an occultist, or an atheist by modern convention.

Regarding Occultism: He detested the mysticism, neo-paganism, and occult underpinnings that Himler brought to the party (specifically the SS). Hitler made it very clear that he considered these viewpoints to be sophistry and repugnant to his own view of the world, but he allowed them in so far as he supported Himler as a leader of the party.

Regarding atheism: Hitler, likewise, considered atheism to be an ideological evolution of Jewish Bolshevism that he believed was essentially responsible for the rise of Soviet Communism. It is well documented from close confidants who surrounded Hitler, and wrote about his views contemporaneously that he believed atheism was an ignorant and dangerous return to the animalistic hedonism of humanity.

Why am I bothering to quibble over these distinctions? Well, for one thing because truly dangerous political leaders generally possess the intelligence, as well as tactical forethought to manipulate and twist at the very heart of the tribal labelism that proliferates through the uneducated masses of society. They then warp these convenient in-group / out-group dynamics to fit the needs of their political ambitions. We see this today, although in a much lazier fashion, with the alliance of convenience between the neo-conservative and christian nationalist movements that have proven to be a foundational undergirding to the "Trump Cult" as it were.

We should all understand the complicated historical relationship of religion and politics from the 20th century. Especially regarding the manipulation of those relationships which lead to the rise of authoritarianism on a scale never seen before or since. Lest we go down that same road again, except the next time will invariably be the last time because the power of the technological panopticon we are now capable of creating would enslave humanity or destroy our species.

PS: If you're interested in understanding the complexities of the religious and ideological positions espoused by Hitler throughout his life as well as the Nazi party as a whole this Wikipedia article on the subject is actually really good.
