To amend the potential misinterpretation I just pointed out, I think the line could be further modified:

“Because you’re a Palpatine? Nobody has a right to those the Force made. That choice belongs to you. Some things are stronger than blood…”

This way the emphasis is less on denying that such a claim is possible, and more so that such a claim would be fraudulent without the consent of both parties. That’s the only requirement, no matter how reluctant it is like in the case of Rey about to strike down Palpatine. Plus, it lines up with what Kylo states earlier: “You… are a rightful Palpatine.”

I’m gonna go back to the Vader and Kylo fight today to wrap that up. Just felt like offering up some food for thought concerning this other idea.
