6. Qui-Gon Jinn
Qui-Gon Jinn is sort of a hippie Jedi, with long, flowing hair, a screw-authority attitude, and a penchant for spouting metaphysical platitudes. His fellow Jedi Masters don't respect him; they think he's a loose cannon. And they're right. To his credit, Qui-Gon did do a pretty good of training his padawan, Obi-Wan Kenobi. But he should have quit while he was ahead. Instead, he becomes convinced that Anakin Skywalker is the "chosen one" and insists on training the boy, ignoring dire warnings from Yoda and the Jedi Council. If it weren't for Qui-Gon, there would be no Darth Vader, and Palpatine wouldn't have had a Sith Lord powerful enough to carry out his diabolical plans. Qui-Gon was responsible for that whole galactic mess, and yet none of it was intentional. Up to the very end of his life, he truly believed he was doing the right thing. Qui-Gon served his purpose by setting up the entire Star Wars saga, but he's done more than enough. We don't need to see him again.
