Yeah, I totally hadn’t considered those visions as lies she’s telling herself, either. That’s some strong character stuff, in theory. She’d be seeing these “visions” as Kylo alludes to her darker nature; this has been her soothing method her whole life more than likely. But I agree with Eddie that we don’t necessarily HAVE to take this approach for both of our edits. Plus, I could see people retroactively saying that it feels like a fan edit because people usually prefer to believe what they’re seeing over what they’re being told.
One important thing worth considering about whether Palpatine creates the Skywalker bloodline or not: it massively benefits Kylo’s character, Luke’s in the sequels, and even Leia’s if we modify her flashback a bit.
If Kylo admits to Rey that the Force created his grandfather as a counter to Palpatine’s darkness, then he’d be admitting that his whole persona as Kylo Ren is a farce. Remember, his whole argument here is that “the dark side is in our nature”. So this exponentially strengthens his own deluded beliefs.
Now onto the characters themselves. Firstly, there is one of two options. Either there was so much evil in a young Ben Solo that Luke saw absolutely no chance of redemption in him, or there are so many evil instincts in Luke that he was willing to strike down his nephew over some bad dreams. Or a combination of the two somewhere. Luke then isolates himself from the galaxy to protect them from himself and what he suddenly believes is a flawed Jedi religion. As for Leia, she uses aggression to take down the brother who’s trying to teach her, and she senses that there is a dark fate waiting for her if she continues being a Jedi at all. So she is too fearful of herself and that to continue at all.
None of this sounds like what should have happened to the offspring of who is essentially Force-Jesus. Yes, he turned into Darth Vader, but that took a hell of a lot of manipulation on Palpatine’s part. It wasn’t something that just switched or snapped like it seemed to in Kylo and Luke. Plus, Anakin was redeemed! He returned as a Jedi. That should have had a greater impact on the trajectory of his offspring.
Now, all of this is likely because the writers wanted to elevate Rey as the main character, so they had to write random reasons for the Skywalkers to be in more minor roles. But the fact that we could actually EXPLAIN why things turned out so bad for their family? It seems like one we should take.
