You say he never fell from the path but I’d argue heavily against that. I mean he didn’t prior to Kenobi but after that? I typically stand by the stance that the only Jedi in the Original Trilogy is Luke and he doesn’t even count until RotJ.

Obi-Wan and Yoda actively lied to Luke about who his father was. They trained him to kill Darth Vader, his father, in what feels like an act of vengeance for how Vader betrayed them. Now I get it, they do have a justification in saying go after Vader but they were insistent on Vader. Not Palpatine. Sure, Daddy Vader is a problem but he’s not the sole problem. Getting rid of him would hurt the Empire but with Palpatine and everyone else hanging around it is still going to be standing very strong. They also can’t claim ignorance of Palpatine considering Yoda did his ‘Kermit on Ketamine’ sequence at the Senate against The Senate. I mean, for fucks sake, Yoda starts trying to die faster the second that Luke starts asking questions. Obi-Wan, a fucking ghost at this point, is still lying to the poor kid and trying to justify his behavior.

Now, like I said, I don’t blame either of them. The loss that both Yoda and Obi-Wan suffered was utterly immeasurable but they were not exactly holding strictly to Jedi ideals and teachings at that point. Flowing through them the hate was.
