I wouldn't say Hitler was an emo, if we're speaking literally.
His jealousy of blonds didn't inspire him to start carving his wrist open, but actually kind of gave him an inspiration to achieve his goal even more, even in denial at not being perfect.
He was renowned for his charisma, and emos lack in that department, and he wrote a book "my struggle" which doesn't implement that he has invoked sad poems, or depressing artwork in there, maybe he just felt like writing an auto-biography on his life. Nothing emo about that...
Having a fringe doesn't mean your emo, it's a style, get over it.
Loads of people blame other people for their problems, I do, for instance and a lot of people in my school do, doesn't particularly mean their slitting their wrists at night.
Overall, I definitely think he was not emo, although I'm not trying to defend the sick bastard.
