I get what you’re saying and I don’t disagree, but for all intents and purposes the movie treats him like a good guy from that point on (“Kylo Ren is dead. My son is alive.”). His part in the climax is completely different than Vader’s, besides the mere fact that he sacrifices himself (which is done completely differently).
I get that the specifics are done differently but it’s ultimately the same story.
