That might be so, but for the audience it’s so convoluted that its better to keep it simple.
I’m fine with Palpatine telling Ren to kill the girl even though he may have other plans for her alive. I don’t lowbrow my edits.
EDIT: The better choice would be to get rid of the whole “make the sacrifice” shit at the end. But that’s easier said than done since it would remove the entire impact of Rey force passing the saber to Ren. Also while editing I did tinker with cutting off the word dead so Ren says “Do you know why the Emperor’s always wanted you?” And the results sucked. Someone might be able to get it to work but they would need to find a sentence spoken by masked Ren that he ends with the word “you” in just the right cadence.
