Hitler killed the Jews because he said that they were the reason that the economy was doing so bad. Hitler also blamed losing World War 1 on the Jews.
the reason why hitler was angry with the jews started when he didnt get accepted in an art school when he was a young lad and the merchants were doing well and they were JEWISH and he was just angry because on that
