He trusted already she wasn't really a killer of innocents just for kicks. I think mainly he doesn't trust her following orders, or not killing Merle. The main reason for taking her along IMO. I think as far as worrying about Michonne killing his boy that is a reach. She hasn't shown to be that heartless. Emotionless yes but not sociopathic like Merle.
But looks like her and Carl have bonded and that is a good thing for Michonne.
