User blog comment:Gundam Legilis/What if the Black Trailer was better?/@comment-11188061-20160312004018

Well, during Black Trailer Blake was still by his side, so Adam's personality is still more leaned towards the controlled kind (because he doesn't want to hurt Blake, even though he probably hurt her plenty already).

However after she left, he is left completely alone with his own demons. There is no longer a conscious to tell him what's wrong and what shouldn't be done, and the monster inside him is literally freed from its chains. Even then Adam is probably still a saner person if he hadn't met Cinder, who promised him power beyond his imaginations and the destruction he has always dreamed about. It's like, here's this defenseless person you want to kill but don't dare due to the fear of the law. But now I've broken the law for you, so do whatever the hell you want.
