Fine, here I go.
The NSDAP won 44% of the vote the year they rose to power, not through democratic proceedings, either, but from domestic terrorism
Any Germans that could vote in 1933, would be around 95 years old or above, so no, the Germans that blame Hitler are mostly dead, you can't blame their children, they did nothing wrong.
The German people that squealed on their neighbors, that destroyed Jewish shops and that ignored the signs of Death Camps (Which weren't in Germany, only in Poland, so very little Germans that weren't members of the party were actually aware of this happening) were facing death or forced labor if they acted differently, so I'm afraid you can't blame them for acting out of constant irrational fear of almost certain death.
Hitler was evil, I'm not going to argue with you about the philosophical intricacies of purity or evil, but the man was certainly motivated by all the wrong things.
Yes, it is possible to justify his actions on an international scale, but the justifications are weak, and in the end nobody can say that the world wouldn't have been better off without Hitler.
Hitler never forcibly took Russia, he never got far enough to be able to claim that he conquered Russia, but rather his army got stuck in a long stalemate with the red army, until they ran out of munitions and supplies and eventually were forced to surrender and retreat.
Hitler wasn't out to pick a fight with Britain when he conquered Poland, he was out to conquer Poland when he conquered Poland, rather England was the fight picker, not that they didn't pick a just fight, but in a way "Britain started it".
Hitler never exterminated Slavs, even though they were an inferior race, according to Hitler's race theory, Slavs were meant to serve the Aryan race, while the Jews were the ones that had to be destroyed.
