i see the Sith as a sort of Fallen form of the Jedi. sort of the like devils are the fallen form of angels. he does not have the power of a Jedi, he must sort of rely on them, thus the conspiracy, he is given the title of Emperor through the Jedi.
had the Jedi not picked up on Anakin, I doubt the Emperor would have found this kid on a random nowhere planet. he was manipulating the Jedi and the Senate while Anakin was invited into this elite political circle and that is how he was discovered. Qui Gon bent the rules a number of times, including changing the results of a dice roll, in order to have Anakin be trained, which is something the Jedi council, including Yoda, was against. Obi Wan goes against Yoda in the OT just like he did in the PT. he trains the unsanctioned, prophesied Skywalker of both generations, in honor of his fallen master Qui Gon's unorthodox wishes. it is nice that Obi Wan somewhat redeems himself for Vader by training Luke.
had Qui Gon not been so rebellious (and through his pupil Obi Wan) it is possible Anakin became a successful racer on a backwater planet and that's it. the only reason the Emperor finds him is that the Jedi find him first. FWIW i think people give the Emperor too much credit. politicians are not that smart, manipulating your way into eternal war is probably not that difficult. as a professional conman he likely tells a lot of lies, yet people take what he says as truth.
don't believe his lies.
