He's the one who plans the entire rescue of Han in RotJ. I believe Chewy tells Han that he planned everything and Han acts completely surprised because Luke is just a whiny kid who couldn't plan anything.You guys must have Luke confused with someone that wasn't a petulant whiner while being trained by Yoda, that failed to lift the X-Wing, and who was successfully goaded into attacking by the Emperor in RotJ. Luke was always a hothead that thought better of it a moment later. This calm, collected, super-awesome Luke isn't someone I recognize from the OT at all.
But then Luke shows up in RotJ and he's calm, collected and thoughtful. Not at all the character he was in ESB. It's obvious that a bunch of time has passed between the two movies because all of his friends are treating him with a lot more respect and he seems to be almost a completely different person.
When he faces the Emperor and Vader, he does so calmly. Though the Emperor tries to make him lose his cool and he eventually picks up his lightsaber after quite a long time of the Emperor goading him. However, once he realizes that he's let his anger get the better of him, he refuses to kill Vader and drops his lightsaber.
We're led to believe that Luke has finally had his breakthrough. He has been grappling with his anger and aggression for the last 2 movies, but as he drops his lightsaber and says "You've failed. I am a Jedi like my father before me." we are led to believe that this is the last time he'll let his anger get in the way. He has finally learned to "let go". He faced his anger and came out the other side, completely getting rid of it.
Which is what makes RotJ my favorite Star Wars movie. It's the culmination of the Hero's Journey. It's the point where the Hero steps up, having finally found his path.
Which is why Luke forgetting all of that and becoming broken hurts me so much and why it colors the rest of the movie for me, even though large parts of the rest of the movie are actually very good.
