Was Napoleon a villain or actually a hero?

Being English, Napoleon has always been made out to be a bad guy, but when you actually read about him, he was basically just a communist in a time of Monarchies and unfair hierarchies. He didn't target any ethnicities like Hitler, in fact he treated the Jews better than they'd ever been treated in Europe and got rid of laws that forced them to live in ghettos. Why do people hate him so much then. Surely if he had conquered he would have united Europe in equality, and got rid of the Bourgeois church leaders and monarchies.
