I've seen this technicality before, but it always feels hollow to me.
Like yeah, hitler changed the world, but he was an opportunist at the right place at the right time when his style of rhetoric and politics appealed to a country going through the aftermath of a world war and the Great Depression.
He didn't change the world because of something clever or intrinsically special about him. He wasn't special at all. That's what makes fascism so dangerous.
To describe him as a supernatural outlier of a person builds a myth that the things he did could only happen under the influence of a single charismatic person.
Putting him on the list and the cover gives him credit he doesn't deserve.
