When the evil Palpatine says, “Good is a point of view--the Sith and the Jedi are almost the same,” we can dismiss this moral relativism as part of the deception of the dark side.
But in a pivotal scene, Obi-Wan says what amounts to the same thing: “Only a Sith deals in absolutes.”
Isn’t that odd? The only thing both sides agree on is that people who believe in absolute good and evil are bad!
I suspect that Lucas realized, after writing "Good is a point of view," that all his friends actually believed that. So he had to make it clear that moral relativism was the right way after all—so he had Obi-Wan say that absolutism was a Sith thing, even though in the actual story, the best of the Jedis show an unbending commitment to absolute Good.
It’s a terrible thing, I suppose, for a writer to invent a religion and then discover that he and all his friends are on the wrong side of it.
The Jedi may claim to be in favor of democracy, but in fact they function as a ruling elite, making their decisions among themselves. They occasionally submit to the authority of the legislature, and they seem to respect the rule of law, though whose law it’s hard to say. By and large, however, they decide among themselves what they’re going to do and when it’s OK to break the law and defy the civilian authority.
They are, in fact, utterly anti-democratic, like a militia that owes nothing to civilian authority.
