Our friend here, the Pope of Rome, who is the perfect example of how the Light side of the Force is stronger than the Dark side. As well as Darth Vader came back to the Light in the last few minutes of his life, just by saving his son´s life from the Emperor Palpatine, the fact that he was a member of Hitler´s youth did not stop the Counsil to make him Pope. Anakin slayed hundreds of Jedi and countless other lives during his rule of the galaxy. Mazinger was a part of the Nazi war machine. Anyway, he probably only killed communists, gays and other such elements.
