I hope he stays evil throughout the whole trilogy. That would put a new twist on things. I don't want these new Star Wars movies to completely ape the original trilogy in every single little aspect. I liked The Force Awakens, but it was almost a complete rehash of A New Hope. It lost points for lack of creativity. I want some original stories and different character arcs than what we've already seen. Here's hoping that the next two films have a lot more originality.
