What were the reasons that made Nazi perpetrates macre against Jewish?

I'm glad someone remembers that this part of history is very important, so lets get back to your question, The Nazis believed that the Jews had stabbed them in the back for many reasons 1. having some of the communists during ww1 be Jewish was sought to be the answer. I believe it happened because they were jealous and hateful towards the innocent Jews. The Jewish people did not do anything bad, no hate actions nothing the nazis invaded everywhere around Europe and took the Jews out, but still to this day i don't know how they had so much power to overrule a race that is so strong to handle anything, the Jews. Thats why i respect all, and give more of my knowledge towards the History of our TERRIBLE HATE CRIMES AGAINST HUMANS.
