well no hitler is not a hero, but to some crazy fockers out there he is. Ali stood firm in his believe to fight what he saw as injustice, a noble belief, not in some crazy belief that he's the ubermensch and that he needs to burn about 6 million "untermenschen" which is what hitler believed and did. It's all relative though, if hitler's germany had won jeah he might well be hailed as a hero today cause we'd all get our asses indoctrinated with nazi propaganda from grade 1 and on.
