This might get me down voted, but I don't think Hitler hated Jews because he had a misconception or two about them or was a result of a honest mistake, I think he would have at least disliked them strongly anyway. This is probably however not true of most German National socialists at the time.

I also don't think he was ok with getting rid of those tiresome Slavs in the East because he had misconceptions about them, he wanted to get rid of them because they where sitting on land that could be used by his tribe. This particular bit is generally part of a very ancient and in humans very viable value system.

A good way to remind yourself of why indifference of a AI god would be horrifying is the realization that its perfectly possible the Hitler had no real ill will towards Russians or Poles once controlled for his dislike of Communism but that the moral worth of them in his value system just happened to be zero.

Humans can and do have very different value systems.
