Reactions to first showing of movie

After watching the segment from El Che a single thought lingered in my mind. Why is it that Hitler has gone down in history for being a malicious killer, unstable/insane, and a dictator that could not be beaten, yet Che seems to hide only in shadows despite killing numerous amounts more and inflicting more chaos than Hitler. Why is it that Che has gotten away with so much? Is it because in the eyes of the people Che has been created into a Hollywood icon instead of a killer? How can a man act in such a way yet we seem to condone it?
