King Henry VIII. He had two wives beheaded: Anne Boleyn and Catherine Howard.

Hitler. He was one of the most evil of people ever to have lived.

It is the only religion which appears to me to possess that assimilating capacity to the changing phase of existence which can make itself appeal to every age. I have studied him - the wonderful man and in my opinion far from being an anti-Christ, he must be called the Saviour of Humanity. I believe that if a man like him were to assume the dictatorship of the modern world he would succeed in solving its problems in a way that would bring it the much needed peace and happiness: I have prophesied about the faith of Muhammad that it would be acceptable to the Europe of tomorrow as it is beginning to be acceptable to the Europe of today.

The number 1 worst historical person in my view is Ed Gein. The things he did to his victims was disgusting and extreme. He was truly evil.
