Problem is that you would have to ensure that Hitlers non-existence (however unpalatable a character he is) does not give rise to a worse scenario, e.g. Stalin running over most of Europe, a worse dude than Adolf taking his place, etc.
Jeez, you mean I hafta run all over history nipping dictators in the bud? When am I gonna have time for my sexy time-travelling companion?
