16 hours ago, Lareg said:The Jedi also had, at least in Legends, the Right of Denial. This left them unarmed (they had to hand in their lightsabers) and stripped of any authority, Jedi only in name. An even more radical approach was to simply resign from the Order as Count Dooku did ebfore becoming a Sith Lord.
Right of Denial was something WotC came up with for their Living Force campaign for the sake of those players with Jedi characters that didn't want them to go off fighting in the Clone Wars, as it was either "give up your lightsaber, or your PC gets retired from active play to go fight in the war."
The vast majority of the Jedi that were active during the Clone Wars were raised with a strong sense of loyalty to the Order itself but also the Republic, which was pretty much the bastion of civilization. Note that the Jedi didn't get actively involved in fighting the Confederacy of Independent Systems until it had become absolutely clear that they were gearing up for war against the Republic. Apart from Dooku, who was in cahoots with the mastermind behind the whole war scheme, none of the CIS leadership was aware the Republic had a large army waiting in its back pocket.
Having been around for a thousand generations, the Republic had more than once seen corruption, and yet it had endured and rebounded, so the Jedi probably figured that while not perfect, the government of the Republic was better than the alternatives, and so felt an obligation to defend it.
While that degree of loyalty might seem quite odd to your average citizen, bear in mind that a Jedi was brought up in a monastic environment that very strongly encouraged a life of service and hardship in the defense of others. We as the audience also have the benefit of seeing the puppetmaster behind the whole thing, something the Jedi didn't due to the shroud of the dark side having fallen and thus clouding things to a degree that Master Yoda, the Order's foremost expert on farseeing, couldn't get any sort of picture, fuzzy or otherwise as to what lay on the horizon.
