Technically Palpatine did die, but in legends, Sith who had left their bodies could possess people. Palpatine had dozens if not hundreds of clone bodies waiting, along with all sorts of scary projects and insidious toys. It took a Jedi master basically restraining his spirit in a headlock all the way to the afterlife to stop him for good.
