Personally i'm annoyed by the polarized nature of the force in the movies and i really wish to see a grey/neutral jedi for once being important.
I don't know anything but another Good jedi vs stupidly evil Sith.
I think Luke was pretty much a grey-neutral jedi... and that's why he was the good one.
During the prequels, and ESPECIALLY during the original trilogy, the original Jedi order is shown to be pretty much as bad as the sith. They are two sides of the same coin, really. I suppose that the rotting oligarchical burocracy the Jedi were supporting *is* marginally better than the chaotical warlordism Palpatine seems to seek as his ultimate political goal, but by how much exactly could likely be contested, considering the Galaxy is already rife with crime, slavery, and injustice during the prequels.
Anyhow...
Consider the following:
- The Jedi Council as a whole is a praetorian guard dedicated to maintaining the status quo no matter what.
- Jedis are banned from forming attachments of any sort, because this might make them stray from the cult's goals. Yoda straight out refuses to help Anakin deal with the (eventually self-fulfilling) prophecy about the death of his loved ones because he shouldn't have loved ones in the first place, and instead tells him the force yadda yadda deal with it.
- Mace Windu was happily going to murder an elected head of state and carrying out a coup de'etat because some teen guy that up to that point HE DID NOT TRUST AT ALL happened to tell him that the man was a member of a rival cult.
- Bonus points because at this point they don't really have any proof or inkling that Palpatine has done anything nefarious -we, the spectators, know that he was orchestrating the whole war, but Mace L Motherfuckin' Windu
knows no such thing. He just took at face value a second hand report that the chancellor followed a different cult than his, assembled a death squad, and went to kill him.
- "Only a sith deals in absolutes. I'll fulfill my duty". Let's leave the oxymoron aside for a moment and consider how fast Obi has gone from "BFF you saved my life 5 times" to "I'm going to murderize you".
Except... oh wait. He doesn't even kill him, really. Instead he maims him and leaves him to presumely burn slowly to death at the shore of a lava sea. Really, all things considered, Vader was pretty collected while confronting Obi Wan during episode 4, when one takes into account how their last meeting went.
In the OT: Both Yoda and specially Obi Wan keep manipulating Luke into patricide. No word on whether they expected Luke to survive such a deed.
It's not like they don't have a contingency plan in the hat, just in case. Even after the "certain point of view" (that's Jedese for "pure utter bullshit") comes to light, both Yoda and Obi Wan keep trying to guilt-trip him into doing it anyway.
BEN
To be a Jedi, Luke, you must (...) face Darth Vader again!
LUKE
I can't kill my own father.
BEN
Then the Emperor has already won. You were our only hope.
And you know what's the funniest thing about this exchange? THAT THE EMPEROR WANTS HIM TO DO EXACTLY THAT SAME THING!
EMPEROR
Good! Your hate has made you powerful. Now, fulfill your destiny and take your father's place at my side!
Except Luke realizes that the solution lies precisely in following his own moral compass, instead of the decrees of cult leaders acting on the whims of unfathomable opposite-but-equal cosmic forces. He just wont kill his own father because in his book it's plain wrong.
And it works.
