If you want to know the truth then you have to let go of the children's story that he wanted to kill jews for no reason other than he was insane and evil. The jewish issue goes back long before Hitler and the Nazis and continues till this day. If you want to do some research, stay away from wikipedia and look into these for a start: Sabbatai Zevi, Jacob Frank, Kabbalah, Sabbateans, Donmeh, Crypto-Jews, Spanish Inquisition, Jesuit founders, Saturn worship, Israel and 911, USS Liberty, The Young Turks, Armenian Genocide, Karl Marx, King Solomon, Bolsheviks, Albert Einstein, The Rothschilds, .........

You will also have to have an understanding of the occult, without that you want be able to see the whole picture. Start with Saturn symbology, Star of David, and Swastika.
