I didn't make a provable claim; my stance is there's no way to know what Hitler really thought of himself and that his writings only necessarily show what he wanted others to think about what he thought and could have been a part of the cult of personality he built around himself rather than his genuine beliefs. Not saying that he did or didn't actually believe any of that, just that he's the only one who truly knew and that thought was forever erased by the hot lead he shot through his head in his bunker.

My suspicion was that he didn't really care that much about good or evil and only spoke about them because it was a means to manipulate others into giving him power, but I wouldn't bother betting money on that because there's no way to resolve such a bet.

It's clear he thought he was doing good for himself, at the very least. Often that is motivation enough, especially for small men who crave great power.
