In Star Wars Attack of the Clones, Anakin’s Mother, Shmi Skywalker, passed away due to the Tusken’s capturing her. Anakin reveals in the novel that he felt it was majorly Obi-Wan’s fault not only that he was held back, but also that he was responsible for her death in the end. I believe if Qui-Gon Jinn had trained Anakin, then things wouldn’t have ended up in the dark side. Vader wouldn’t exist, and Anakin would restore peace to the galaxy.
