Please don’t remove the “I never wanted you dead, I wanted you here”. It reinforces how Palpatine is manipulative and a liar.
While I agree that those lines were most likely written with the intention of them being manipulative lies, it works far better for them to be gone, and not only because it streamlines his plan and makes it less confusing.
Palpatine’s main goal with Rey is to make her as angry at him as possible. If he says that he never intended for her to die, that is exactly the opposite of what he should be trying to do. He needs her to want to kill him, not appreciate him.
