Now perhaps the german heritage, culture, and way of life leant itself to the rise to power these individuals achieved, but that doesn't mean the germans were themselves all evil and despiteful to the core.
It wasn't the germans that caused the rise of those individuals, that was caused entirely by a little thing called the treaty of versailles. Blame the English, the French, and the Americans for the Nazi party. I would say they caused it more with that treaty than any other single act.
