Not one of you fuckers has made a case of how these people were worse than Palpantine
Its this simple. In both the origional trilogy and the prequel trilogy the character never scared me. He was bad sure but in an objective way.
Darth Vader is scarier, starting with physical presence but then add this in. He was indeed supposed to be "the chosen one", the best of them(of us ). And due to a combination of tragedy, fear, hate, and manipulation became the child killer and terrifying villain. Because while Palpatine was a sociopath and therefore irredeemable Vader was the Good Man turned bad.
We fear that more because but for chance it could be one of us. He is a mirror we don't want to look at. The best villain is the one with a reason that actually isn't selfish. Vader turned to the Dark for arguably the right reasons. And we as people fear that far more. That our own decisions could take us fown the same path.
The reveal he was Luke's father remains to this day one is one of the great moments of film. There are compilations on Youtube of parents showing it to their kids and the kids losing it. Because its also a moment for kids when they realize parents can be flawed. The looks and denials are amazing.
Thats why Palpatine runs less. He just didn't hit home the way Vader does.
