Was Hitler objectively bad?

[Minimalist]

A reason based on racism & biggotry. So, your justification relies on the merits of revenge. You think they would have learnt their lesson the first time around the block.

Actually, the issue which propelled Hitler into the limelight was the perception in Germany that they had been screwed at Versailles. Yeah - he put all his racist claptrap into Mein Kampf. Apparently either no one cared or anti-semitism was real popular in xtian Germany. I sort of think the latter.

Perhaps he merely did. Oh, perhaps merely is the wrong word too use, as it resulted in the complete anialation of the Third Reich.

Lots of rulers throughout history have made that mistake. Tougher on the followers than the ruler.

But they didn't invade a sovereign country.

Tell that to the Dutch.

This is beside the point of the original question anyway. You have gone way off tangent to support your own assertions.

There was a point to the original question?
