15Qui-Gon Jinn Knew Anakin Would Turn Evil
Another one of many Reddit theories that force us to reevaluate the prequels, this one claims that Qui-Gon Jinn was aware that Anakin would bring about the destruction of the Jedi Order, and pushed for his training anyway. The theory points to the fact
that everyone around Jinn felt the boy was too emotional, too reckless to make a good Jedi, and yet Jinn persisted, ignoring all the obvious signs and taking steps he knew would only alienate Anakin as he got older.
Things get even crazier when it's implied that Jinn was working with the Sith throughout The Phantom Menace, and that he orchestrated his own passing as a means of guilting Obi-Wan into taking Anakin on as his apprentice. If true, then Jinn may be the most devious, manipulative character in the entire Star Wars saga. If not, which is the more likely outcome, than he was just a guy who made the worst possible judgment call imaginable.
