Well, that’s kind of my point. Everyone will now become a good guy. We’ll have an entire series where everyone is prequel Anakin, and Kylo, and Phasma who didn’t mean to do bad things. They are just misguided kids making mistakes and killing people because some bad emperor or bogeyman tricked them into doing it.
Well Phasma wouldn’t necessarily have to be one of the good guys if she left the First Order… They could take it in a different direction where she is more of a grey character. It was just an idea to possibly explain why it seemed she complied with their demands so easily.
