Qui-Gon Jinn.
Often viewed as a renegade, a wayward warrior of the Jedi Order who refused to tow the line. Jinn wasn't above using the Force to influence situations, manipulate turns of events for what he believed was the greater good. Perhaps even right down to the nature of his own death.
But what if Qui-Gon, in his own rebellious way, was right? What if his new, fresh approach to the teachings of the Jedi had been the true path?
Yoda had been training Jedi for 800 years, and it seems that his attitudes and tactics changed little over the years, while the galaxy - an ever changing environment - changed around him.
Jinn had a different view. He believed in the living Force, and yet he also believed in the prophecy of the Chosen One, an ancient teaching that said one would come to bring balance to the Force.
Anakin was certainly the Chosen One, but who would teach him? Qui-Gon? No. When he took the boy under his tutelage to the Council they rejected him. So Jinn knew he needed to do something special to bring Ani into the fold. And during the fight against Maul, a foe that Jinn knew was more powerful than he was, he found the way.
Meditate, prepare for the next level and become one with the Force.
But was Qui-Gon the first to do this? How did he achieve it? And why?
We know that, as Ben said to Vader, "If you destroy me now I'll become more powerful than you can possibly imagine."
Did Jinn know that from beyond the grave, where he was past physical harm or dark influence, he could dictate events to the Jedi's advantage? Ben followed the same path as his master to great effect.
But as a consequence of this Anakin was passed into the care of Obi Wan Kenobi. And we know that, while he got things right with Luke, he got things disaterously wrong with Anakin.
So, my question. Was Qui-Gon's biggest error allowing Anakin to pass into the care of Obi Wan and his training?
