The counterpoint to the claim is that he supposedly "tested" his cyanide pills on his dogs as the Red Army closed in on the bunker. I'd argue that every pet owner is going to euthanize a pet at some point and there probably couldn't have been a crueler act than letting the Soviets capture a dog they knew was yours, if you're literally Hitler.

Hitler wasn't a demon in a human suit, he was a person and people are quite often the kind hypocrites that can refuse to eat meat because of animal cruelty while supporting slave labor and human slaughterhouses.

Every vegetarian capitalist does it every day whether they admit it or not.
