Some of it is conflicting, like his opinion on people of the Middle East and Asians.
And other bits of it changed, like his Anglophilia.
"his...beliefs"
We don't even know for certain if Hitler was a Christian or an agnostic or atheist.
There are quotes where he mentions Providence (I think that's another word for God) but then we also have him saying that Islam is a much better religion than Christianity.
There are extensive records, but they are often contradictory or obviously biased (like Speer's book).
Hitler was no Christian. He sought to create new specular institutions to replace Christian Faith. He rejected the divinity of Jesus, and of course deigned he was a Jew. He hated the moral codes of Christian teachings. He talked of hanging the Pope, in the middle of Vatican Square. He spoke well of Islam because he thought it was a better religion for warriors. In his models of the New Germania, and Linz there are no churches, or any places of worship. The only temples were stadiums of secular worship, and the glorification of war.
Hitler believed some nebulous Providence had set up the world as an arena for biological determinism, where races of humans could fight for dominance, and survival. In his world view man was just another animal, of no greater value, or higher purpose then survival. Hitler reveled in the slaughter of human beings, but thought it was immoral for humans to "enslave, and eat animals." His vegetarianism was both moral, and because meat upset his stomach. Nazi education taught children life was a Darwinian struggle where the strong preyed upon the weak, and the weak deserved their fate.
I remember a Nazi film of a classroom. The children watch a film of a Fox, or Wolf, I can't remember killing a Rabbit, and telling the class this is how the world works. A more sensitive boy looks upset, so the teacher asks him why? He says he feels sorry for the Rabbit. The teacher mocks the boy, and the rest of the class laughs at him. Look at films of children measuring the noses of classmates to see who is a Jew, or member of other inferior races. No decent human being of any faith, or no faith teaches children those kinds of values. Those teachings have nothing to do with Christianity, or any other faith, it was all about hate, not love, which takes us back to the question of this Thread.
Hitler had little love in his heart for anything. His mind was twisted, and dark stemming from his difficulties in relating to people. One of the reasons he was rejected as a young man, by the Vienna Art School was his almost complete inability to draw people. All his life his relationships with people were strained. He had difficulties making friends, and relationships with women never worked out. He almost always ended friendships with bitter feelings of betrayal. He needed to have relationships where he was totally dominate. Heathy relationships are based on trust, and a sense of equality, and respect, Hitler was not capable of giving those things. A narcissist can't give love, because they never felt they received the love they needed to feel secure. A narcissist is a very damaged person, who can never be trusted with power, it will never end well.
