What if Hitler committed suicide early in life?

People have always said that life would be better if some of the tragedies in the past could have been prevented, but think of it this way though many of these people you mentioned did horrible things these tragedies have influenced other nations and with all of that creates the society we live in today. It changes the entire course of history maybe for the worse if one of these men did commit suicide before their time. Take Stalin what if he had died early there would have been another communnist dictator and. maybe the beginning of the cold war might have lead to an actual war with the use of nuclear weapons
