I'm not "just" catagorizing him as evil. I'm taking into accounts his horrible actions that were indeed overly evil in nature. Just because he may have had some decency in him doesn't mean he still can't be evil in nature. All we have to go on is hitlers actions, and needless to say, they were indeed evil.
"To me evil is doing something intentionally when you know it is wrong. I think we are instilled with morals from birth, where we know what is good and what is bad, right and wrong, we learn from those around us, you know the drill "Don't take what isn't yours, or don't push your sister, etc etc.". Knowing fully well you are doing something you were taught is wrong is evil in my opinion."
I believe this statement would hold true for Hitler, wouldn't you agree? Surely he knew that killing millions of people out of spite is wrong. "don't kill people" is one of the most basic laws of human decency, the fact that he was able to kill so many people is to me proof that he is indeed evil.
