If you read hitlers book mein kampf very carefully, noting every philosophical paragraph he wrote, you will find he is the most tragic victim the discipline of altruism has ever caught.
Also, if you have read ayn rands philosophy, you will easily find the mistakes he committed.
He wrote about the evils of the parlimentary system, which is run by a cohurt of incompetent majority. He wrote explicitly about the importance of individualism; about the contribution of a single, hardworking individual to a society.
Hitler was not a moron at all. He worked hard, he analysed every issue from every viewpoint. But his one and only error was this : he decided to joined politics. He decided to jump into the same pool of thugs he had criticised before.
Everything, including the holocaust is secondary. The primary error in him was he fell to ALTRUISM. Read Ayn Rands philosophy of reason first, and then try to decipher the meaning of hitlers desperate book.
