That's because you view things like this as isolated acts done by a few people. But don't forget, only 1/3 of US voters tried to stop a man who openly declared himself a fascist, had already had a direct hand in the spread of a world wide plague that killed millions.
The "they didn't know what they were getting into" excuse is no longer valid. And yet 2/3 of voters were fine with him being reelected . The reason those people weren't dragged from their mansions and beaten to death was because of all the other monsters who were protecting them. The people who weren't committing atrocities themselves, but benefited from it enough to help it keep happening.
