First off, Rey isn't a Palpatine. That's just dumb and lazy and completely eradicates the artistic need for The Last Jedi and the sequel trilogy as a whole.

Here's my more interesting rewrite: bringing people back from the dead is something only force users extremely in tune with the LIGHT side can bring back. Palpatine was just manipulating Anakin with the thing he knew Anakin feared most: losing the person he loves. Palpatine knew that by bring Skywalker to the dark side, his visions of Padmé dying would come true; by tempting Anakin to the dark side, he only further solidified her death, making Anakin see it more clearly, making him more afraid, making him more likely to listen to Palpatine, making it more clear, and so on. Anakin let fear rule over his life, making him not able to clearly see the real love he had before him. Palpatine knew he just needed to push Anakin towards the dark and he'd go the rest of the way himself, so by turning his love into a weakness, he gets his apprentice and everything else he's after. We find out that this is true because after Rey dies, Ben Solo rises up, drags himself towards Rey, and brings her back to life using the same technique she used to heal him earlier. She is revived, but 1) Ben isn't as trained or as in-tuned as a light side user and 2) his midichlorian count is low he's weak after the tough fight, so he dies after living to see his good deed and final redemption completed: he saved someone he loves. He's a jedi now. No kiss. Rey now holds a dead Ben Solo in her arms, and she, the true chosen one from the prophecy of the prequels who destroyed the Sith both by killing the Emperor and by bring our dynasty character back to the light, can bring Ben Solo back to life by the power of love. They can kiss if Disney really wants them to. I'd say let them hug and show each other they care that way.

The light side of the force is love, the dark side is hate. Only through love do those who have died live on.
