I somehow feel like Nietzsche would disagree with these teachings. He seems like the kind of guy that would agree with warlords that invade and pillage villages, with dictators, etc, because they're "strong", and would disagree with people like Samael because he has compassion for the weak. He even said weak people should commit suicide!
I'm not saying we should be weak, of course not. But what Nietzsche says goes against the fundamentals of religious thought. His philosophy seems more like Lavey Satanism or Aleister Crowley occultism, which have a line of thought similar to this: "All that matters is power. I need to gather folllowers and admiration for myself. The weak are weak forever, the strong are strong forever. There should be a slave and a ruler. Because I rule I am better than others. Poor, disabled, lonely, depressed people are lowly, and we should increase their suffering by ignoring their pleas and lording our success over them. Let the weak drown in envy and misery, and don't let them get in the way of the enjoyment of the strong, etc".
Perhaps Nietzsche got too arrogant and that was his downfall?
