I don’t think the Resistance will turn bad but I certainly think considering their precarious political position there’s a possibility they might not always seem the straight up “good guys.” It’s possible that they just continue to remain the obvious heroes (like the Rebels) but they’ve been set up in a way that isn’t as cut and dry as in the OT (even if TFA doesn’t necessarily portray it as such, it’s still a clear decision that’s been made) and with EpVIII likely being the darker chapter I could see them going to some interesting places (Empire did add complicate the black and white morality after all with Lando and Vader’s reveal).
