Palpatine is such a confused antagonist for both Rey and Kylo's dark side conflict because he can't really offer them anything they want through the dark side. He doesn't offer Rey family or belonging, just power, and she's indifferent to it, and Palpatine can't give Ben Rey.

One of the most laughable elements of the story is how little Ben is even taking Palpatine seriously. "He has this big plan for us but whatever let's just kill him together and maybe kiss afterwards" oh I'm so glad we found out that Palpatine was haunting him for his entire life.
