If Darth Vader shouldn’t be space jesus I don’t think the emperor should have been space Voldemort who keeps coming back. I was fine enough with a Skywalker Sith lord with his wannabe ex Jedi anarchists, to me that would have been a fine evolution, we killed the big bad but there are still problems!
Course as everyone already said execution is everything, if I had the choice between an underdeveloped Palpatine or underdeveloped First Order I’d lose the order.
