Why?

Hitler and the Nazis felt that they were supposed to elimanate many different kinds of people, that is why he started killing jews. Well, I don't understand why he was doing that, so I am just going to make some hypothesis about it. Hypothesis 1: He blame jews for German's great depression. After World War I, many countries asked German to pay money. That caused depression within German. I didn't know why Jews had something to do with that, but mabye he thought that German lost World War I because of them. Hypothesis 2: He thought that Jewish people were the disaster. Jewish people brought bad things to them. He elimanated them, so that the world will be peaceful (mabye, who knows?). Hypothesis 3: Hitler didn't like Jews. This is the most possible reason that he killed so many jews. He just distested them, he thought they were freak, idiot, or monster. Anyway, these are just hypothesis of why Hitler wanted to elimanate many different kinds of people, he thought that different kinds of people would destroy German. Well, I am glad that he's plan didn't succeed. If his plan succeed, all asians will be killed, including Japanese (they would against each other eventually if the war was longer). I think it is better to have many kinds of people exist on this world. People can learn from each other. Killing doesn't any problem, it only make problems.
