How to give the main points i have in my essay and make them sound good?

Question

anonymous · Answer

Some people call him a monster, others call him a genius. Whatever his title is, nobody is able to take away the fact that Hitler changed the world forever. Adolf Hitler was one of the most bloodthirsty dictators history has ever known. He is famous for the mass murdering of Jews. Hitler rose to power because of the Nazi Party. He was one of the best speakers of the Nazi Party, which made him rise to the position of a dictator. Elie Wiesel in the novel Night explains us his horrific experience and how Hitler made the Germans think that Jews were not anything more than animals. Hitler had proved himself as both a monster and a genius.
