I’d embrace the idea of the Jedi being kind of a cult. The Jedi, on their quest to defend peace and justice in the galaxy, have tried to systematize good and evil to help them understand what their quest even is. I like the idea of the Jedi thinking Yoda was the Chosen One, so maybe he, or some other legendary Jedi who deserves that level of respect, would have defeated the Sith, established the current Republic and a new Jedi order, and came up with a perfect moral code which always illuminates the greater good. In the 800 or so years since this, the Jedi have set out on perfecting both themselves and the galaxy.
The cult-like behavior comes from their sheer commitment to the greater good. The Order is socially engineered so all of its members always prioritize the greater good. They train Jedi from birth so they never meet their family and prioritize them over the greater good of the galaxy. They don’t allow Jedi to fall in love or even have friends because the galaxy’s history books are full of Jedi who turned to the dark side for their friends. It’s dehumanizing, but the Jedi justify it because the Force gives you an immense amount of power, and if you can’t give up your own humanity for the greater good, you don’t deserve that power. Anakin, the one who wasn’t brainwashed from birth, who will fall in love and have a child, is going to be the one who ultimately destroys the Jedi Order and hands the galaxy over to Palpatine.
The Jedi are still flawed though, and if I were to actually write this I’d like to frame it to make the argument that the greater good itself is not for the greater good. The Jedi and the Republic tolerate slavery because the effort to end it would cost many times more lives than it would liberate, and (temporarily) tolerating some evils is for the greater good. But you can’t exactly tell a slave that their slavery is a good thing, and if it turned out that the Chosen One is a former slave, you’re going to make a natural enemy of him by continuing to tolerate slavery, even if he recognizes ending slavery would let out more evils than it would abolish.
Anakin’s fall to the dark side has more to do with the Jedi’s failings than his own inclination toward evil. Anakin’s respect for all the good the galaxy’s done at first puts him on their side. But as it becomes more clear to him how much evil they tolerate, he becomes disillusioned with them. When it becomes clear that he’s the Chosen One, not Yoda/whoever, and their arcane rules prioritize the greater good over him fulfilling his destiny by ending the war and defeating the Sith, he becomes radicalized against them. He embraces fear because it’s a natural reaction to danger, anger because it’s a natural reaction to injustice, and hate because it’s a natural reaction to evil. He turns to Palpatine and the Sith, not because they were the real good guys, but because in a galaxy where moral thinking is so completely dominated by the dishonest, delusional, and ineffective Jedi, the only option he really has to turn to is the Sith, who definitely do not give a damn about the greater good, but don’t force him to tolerate slavery and don’t stop Anakin from ending the war destroying galactic civilization itself. With the Sith and the Empire, the galaxy is his to shape according to his will, but radicalized against the extreme selflessness and peacefulness of the Jedi, he becomes a brutish tyrant whose will becomes just as much of an evil as what he once fought against.
I’d like to reconstruct this in the ST. If the PT Jedi’s failings were that they prioritized the greater good over the individual good, and there’s this idea that in the ST that the Force is to become decentralized, maybe Luke and/or Rey teach the galaxy to defend their own personal good. The galaxy shouldn’t have one group of people defending peace and justice, but everyone should be defending peace and justice in their own lives. The Republic, too, would have to go, because there’s no way to enforce one singular greater good over trillions or quadrillions of people in the galaxy. Someone’s always going to get fucked over for the greater good, and some people more often than others. The political status quo after Episode 9 would be a network of small, local Republics which keep order and peace on a small scale. This is bittersweet, because without the institutions that keep galactic civilization together, civilization can not exist on a galactic scale. But that scale of civilization led to the tyrannies of the Republic and the Empire, and the hell that the Clone Wars and the Empire were weren’t worth the luxury of galactic civilization.
