I think it’d be more consistent across the ST to go the other route and imply that Palpatine did want her dead throughout her life until Ben Solo is redeemed at which point he goes ahead and tries to corrupt her.

I think removing two lines would help make this clearer: Finn’s line after mining from D-O, “He wanted her alive,” and Palpatine’s, “I never wanted you dead, I wanted you here.”

And, sherlockpotter, I think that could’ve easily been a good way to go if they’d had that approach when filming or possibly when editing, but I’m afraid it feels to muddled to go with.
