I've often thought about this quote from the Legends novel, Dark Lord: The Rise of Darth Vader: Anyone who thought that the Jedi were responsible for having brought the empire down on Kashyyyk had no understanding of the nature of power. From the moment the troopers of commander Gree's brigade had turned on Yoda, Unduli and Vos, Chewbacca, Tarfful and the elders of Kachirho had grasped the truth: that despite all the rhetoric about taxation, free trade and de-centralization, there was no real difference between the Confederacy and the Republic. The war was nothing more than a struggle between two evils, with the Jedi caught in the middle, all because of their misplaced loyalty to a government they should have abandoned, and to a pledge that had superseded their oath to serve the force above all. This paragraph should be an indicator that that the Jedi were not the villains in this scenario. They were simply doing what they thought was best for the galaxy and it's people. The most interesting part about this paragraph is the implication that the Republic was no different from the Empire that it eventually became, and that the Jedi should have quit trying to save it. They were better off going back to their roots of focusing on the will of the Force, rather than being tangled in bureaucracy. Ultimately, that's their tragedy, that they felt loyal to a government which, at the end of the day, turned on them and sided with the real villain.
