Hitler's National Socialist philosophy really contained hatred for only two main groups: Jews and Communists. As far as being ruthless dictators, Hitler and Stalin shared a psychopathy, but the Russian Revolution helped define Adolf's beliefs, and in the end, changed the course of history by leading, at least in his mind, to Hitler's need to invade the Soviet Union. It was his downfall.
Hitler was only 28 years old in 1917. He was a war hero from WWI and in 1923 he joined a Worker's Party that tried to overthrow the German Government. He went to jail were he wrote "Mein Kampf." Hitler had no international power or influence until after his release from prison.
After WWI Russia was poor. The people were hungry and ready for a revolt. The revolution was led by Lennin.
Even though Hitler was not involved in the Revolution of 1917 Germany was. "Negotiations with the German side were conducted by a delegation of Bolsheviks. Historian Oleg Platonov insists that part of them (to be exact, Leon Trotsky, Adolph Yoffe and Lev Karahan) were directly involved with German intelligence." They eventually had a treaty with Germany and without this treaty the Bolsheviks could not have survived financially.
