I personally think it would fit better to replace Palpatine repeating the “to cheat death” line that doesn’t do anything beyond being a callback. Either way, I think this change would accomplish a few things. First, we get a stronger explanation and understanding of Palpatine’s true nature and means of survival at the beginning of the film rather than the end. Second, it provides a good reason for why Kylo didn’t just immediately kill him. And third, it creates dramatic irony during the climax, because we know what is at stake if Rey kills Palpatine, but she doesn’t. So hopefully the audience would react by thinking, “No no no, Rey, don’t do it he’ll possess you!”
Seriously, this works on so many levels. I don’t get how JJ and co could have written such a terrible climax with Palpatine literally giving reasons for Rey not to kill him. That’s beyond gloating and full on nonsensical dialogue where BOTH parties suddenly become stupid.
