Oh, that is obviously true. And I would say 'Don't let Yoda and Obi-Wan manipulate you into doing stuff you don't want to do' is definitely a goal of his by at least the start of ROTJ. But I would argue that is an eminently reasonable goal. :P

And I think he was definitely ready to go for pushing Vader toward the light every chance he got. But I just don't know that I'd consider a major goal of his, in the sense of something he was shaping all his choices around. He ever really seeks out Vader, or does anything in that direction, unless it's specifically toward an immediate goal of protecting Han and Leia. I kind of feel like he *knows* it's an objectively deranged goal, so he's still just sort of dancing around it and waiting for the universe to push him in its direction if it wants to.

But yeah. The Force complicates the question of Luke's choices a lot.
