As I said, even if this character is a good/evil guy, it's the reaction we take issue with. There is no coherence to that reaction regardless of his alignment. I would much prefer this character make a tactical retreat or be fleshed out as a true reveal and boss fight of his own, rather than what they pulled out. And the "pick your flavor of ceremorphosis" three color option ala Mass Effect 3 really does write the story into a corner and make possible post-game expansions so much harder because this is an impossible branching to reconcile into ongoing post-game stories.
