How is this still happening? How are BOTH sides of the TLJ debate still misinterpreting the ending of ROTJ? Luke didn't drop his saber as a statement against violence in general - even violence against evil! FFS!! That interpretation is mind-boggling. But equally mind-boggling is the interpretation that Luke did it to spare Vader from death out of mercy for his conquered victim. WHAT!!?
Luke didn't want to kill his father. But Yoda and Kenobi both let him know that he had to confront Vader. So Luke relied on reaching the remnants of Anakin within Vader. His "confronting" of Vader was to bring himself before him by surrendering on Endor. His intent was to convince his father to turn on Palpatine and save himself, his family, and the galaxy. But Luke was able to do this only because, if he failed, his friends would still end up destroying the Death Star and taking Palpatine (and Vader) with it. Luke's intentions were entirely based on the Emperor BEING KILLED!!! That was the end game. When Palpatine showed that he was aware of (and prepared for) the Rebel assault on the DS, everything changed for Luke.
At that point, killing the Emperor
himself was Luke's impulsive reaction to save his friends from dying. And Vader stopped him. So Luke was forced to keep the saber battle going just to survive. But when he got a chance to hide, he took it. He still didn't want to kill
his father. This came mere seconds after very much wanting to kill the Emperor. Luke only re-engaged Vader when Leia was invoked as a potential target for converting to the Dark Side. He stopped himself from killing Vader when he heard Palps laughing, looked down at Vader's newly-created stump where his hand used to be, and then looked down at his own hand that Vader had once sliced off. He realized that he was in danger of becoming just like Vader, and being corrupted by the Dark side. That's when he tossed his weapon away.
What people are conveniently forgetting is that even after Luke stood his ground in refusing to become an instrument of Palpatine, he still realized that violent resistance was the only way to survive. When he was being attacked by the Emperor's lightning, Luke called out to his father for help. Luke's cries were not to say, "Daddy, please
talk this guy out of roasting my ass!" It was more like, "Dad,
kill this mother ****** and save me!" And Vader did.
I'm pretty sure that Lucas wrote it simply enough so that even children could understand, so it's hilarious (and sad) that adults are still missing the point 35 years later.
