I’m also gonna drop the newest Luke part here:

Just to clarify, Palpatine can still have a hand in how they’re created even if the Force itself was the one that made them. Palpatine uses the Force like a tool and tries to bend it to his own will. That’s the dark twist in what Luke says - they were made to end (kill) him. He wanted Anakin to eventually kill him in anger so he could possess him, and now Rey is on the same path as he was. Palpatine was twisting the Force’s good intentions for his gain throughout the entire saga.

About the Rey line, I can share a few options for people to rip the “am” off of. But it has to be sourced from her quiet(er) lines from earlier in the film.
