Mangley, part of your post is actually incorrect
Alec Trevelyan is two versions in GE:S
Trevelyan = mi6 (before scarring)
Janus = Janus. (with scarring)
Anyone arguing the semantics need not. I see it as symbolism. Whether he was bad always is beside the point. He was unharmed before the explosion and that is how he is portrayed by our game on team mi6. Then he was punished for his deception and became far more villainous with a revenge plot. It's how it's been planned for well 4 years now and appears in media updates along the way.
