In the climax of The Rise of Skywalker we have
Palpatine goading Rey into killing him, which would apparently "turn" Rey into the Dark Side. The Resistance fighters are also getting pummeled by the Final Order fleet.
What really bothered me while watching this is there seems to be a very easy and obvious way out of this dilemma. Were I Rey, what I would do is
Strike down Palpatine, assume command of the Sith, call off the Final Order fleet (thereby saving the Resistance) and then dismantle the Sith from within.
Heck maybe I'd even command the Final Order to just hold their fire and let The Resistance go to town on them.
Easy peasy lemon squeezy. Why couldn't Rey have done this instead?
The impression I get is that if and when Rey turns, she gets "brainwashed" and so could not act rationally, could not pull off this brilliant plan of mine. I find it very difficult to buy into this. For one, had Rey turned, her circumstances don't exactly put her in a bind; there aren't any Jedi Masters around about to arrest a Sith Lord and whose hand Rey can cut off, turning the tides. Also, if my little knowledge of Star Wars lore serves me right, turning to the Dark Side is more a switch of allegiance, of principles, and does not "brainwash" the Force user. So what gives?
