No, actually I disagree with a lot of what he wrote, because while there are elements of truth, it all starts with an ultra pessimistic view of human nature at its core. If the first principles of a theory are rotten then everything else collapses, even if it has interesting and prescient ideas at the edges.
The atrocities he committed were just effects of his extremely anti humanistic views. So no, I’m not going to take much from anything he said.
