5. Luke Skywalker, Jedi Idiot
Luke seems like a pretty smart guy in the movies. Not brilliant, and way too impulsive, but he has some definite gravitas and wisdom by the end of the Saga. Not exactly a person youd expect to fall for every crazy cult that comes his way. But he gets brainwashed and converted so many times. The most memorable is when he straight-up fell to the dark side. The clone Emperor (another whole thing, dont get any fans started if you know whats good for you) decides he wants a new Vader, so he somehow (I dont remember the specifics) gets Luke to his lair and manages to convert him to the Dark Side. But thats not even the stupid part. The stupid part is that it is revealed to be a clever plan of Lukes. Fake fall to the Dark Side, then destroy the emperor. Shockingly, a plan that clever completely blew up in his face, and the Emperor points out that he has actually fallen to the Dark Side. But he walks away apparently unscathed, failing to learn any lesson.
