I don't understand how you would neutralize Vader without killing him. If you could give me an example, then I could at least understand what you mean. You mentioned in an earlier post that Kenobi should've taken Vader prisoner. I don't get how an Imperial fugitive could safely imprison a Force-powered, high-ranking Imperial authority without resorting to crudely burying him somewhere without access to sustenance. And since doing that would effectively be the same as killing him directly, it shouldn't be an option. Not for a Jedi.
Sure, he could've taken the lightsaber like he did in ROTS, but the odds of it ever becoming a costly mistake down the road are long. Sith shouldn't multiply like gremlins. Kenobi accomplished his mission of buying the escapees time to get to safety. That was his function as a Jedi. In so doing, he kept himself alive and was able to incapacitate Vader without resorting to murdering him. So fine, I give him an "A-" on the Jedi grading scale with points only taken away for leaving the lightsaber there.
I just don't know what more Kenobi could do to neutralize Vader. He crushed Vader's chest box, which is his life support system. He left him kneeling on the ground gasping for breath. Anything more would be killing him, either directly or indirectly.
Obi-Wan is not the Punisher, and Jedi aren't vigilantes. Add to that the complicating factor that this is still the same guy who was like a brother to him. This show established Kenobi's torment for ten years having thought he'd killed Anakin on Mustafar. What logic would there be in establishing all of that just to have him go through the whole ordeal again?
Luke Skywalker was a heroic Jedi for not breaking their values by going through with killing his defenseless/beaten father. Obi-Wan basically made the same choice. The only difference is that Vader couldn't stand watching his son get roasted and doomed to the same tragic path he was put on 20 years earlier. But that's nothing more than Luke being rewarded for doing the right thing. Kenobi did the right thing and didn't need to be rewarded for it.
And again, when I say "doing the right thing," I mean that strictly within the context of established Jedi values, and not as a general moral/ethical question. And when I defend this aspect of the story, I'm not defending the entire series which I felt was mostly terrible prior to the finale. But in the instances (rarer as they are becoming) when I feel lore has been maintained and treated properly, especially when it comes to defining Jedi virtue/actions, I'll defend it.
