Hitler was a Catholic, although his animosity against the Jews was not for ethnic reasons - it was purely political. This is where the difference between Zionism and Judaism comes into play.

Hitler was raised in the catholic church but abandoned it age 18, he said he'd carry out certain things to please the church, and public persona, but he did not believe that Jesus was divine, and saw Christianity as a belief for slaves, he believed it to be a contradiction of natural law, and survival of the fittest. Hitler believed like others that the Aryan race was the superior race as the most evolved, this was a belief that many of the elitists held. Darwin himself in The Descent of Man describes Australians, Mongolians, Africans, Indians, South Americans, Polynesians, and even Eskimos as “savages:” Darwin explains that the “highest races and the lowest savages” differ in “moral disposition … and in intellect." Darwin says that savages have “low morality,” “insufficient powers of reasoning,” and “weak power of self-command. Quote “How little can the hard-worked wife of a degraded Australian savage, who uses hardly any abstract words and cannot count above four, exert her self-consciousness, or reflect on the nature of her own existence." imperialism. Quote:- “From the remotest times successful tribes have supplanted other tribes. … At the present day civilised nations are everywhere supplanting barbarous nations." The “western nations of Europe … now so immeasurably surpass their former savage progenitors and stand at the summit of civilization” The gap will eventually be between civilized man “and some ape as low as a baboon, instead of as at present between the negro or Australian and the gorilla." However, he wrote in his diary that “the white Man … has debased his Nature & violates every best instinctive feeling by making slave of his fellow black” Darwin got most of his ideas of evolution from his Grandfather Erasmus Darwin, he was more concerned about a superior intellectual race which is why he interbred with the Wedge-wood family and was oblivious to the importance of "spreading the genes about." Very much a eugenicist. Hence, with Hitler and his ideologies and human experiments who also held a eugenicist approach, which the Americans took to their country at the end of world war 2 "Operation Paperclip."

His own. He thought he was god. He used religion opportunistically and deceived the public, pretending to believe when he didn't to persuade them.

He was raised up a Catholic child, but after he left home he never went to Church again. He also sent many priests and nuns to their doom in concentration camps. Claiming he was Catholic is incorrect. Here is a link describing his thoughts on the issue; https://en.wikipedia.org/wiki/Religious_views_of_Adolf_Hitler

Hitler grew up in the Catholic church, and as he came to power, he became an Atheist. That's why in the 1930's the Nazis carried out public burnings of books as a statement that Hitler was supposedly their savior.
