I gotta agree with all of them (except #1 and #2 which are stretching things a bit), with a caveat about the Wicked Witch of the West - remember, she never existed at all. She was a product of Dorothy's subconscious and allowed her to process her fears and anxieties about growing up, so by being wicked, the WWW contributed positively to the successful integration of Dorothy's adult personality.
Or something along those lines. In any event, the WWW was "right" in that sense because she was necessary to the whole process and was an aspect of the protagonist's own persona.
You could make a good case for putting Palpatine on that list, simply by virtue of him being the only person in the galaxy with half a brain. If the Senate and the Jedi are really so stupid that they couldn't figure out his game or even suspect him until it was too late, they certainly should not be allowed to run any self-respecting galaxy.
