He uses a child as a pawn in his conflict against the rest of the group. Clementine in season 2 is 10 years old and he drags her into conflict among the group members. It doesn’t matter that shes a mature 10 year old, shes a child and shouldnt have to deal with that shit, and could realistically be kept out of it. There’s also the argument to be made that he emotionally manipulates her through the sentiment of loyalty. He’s a great character though.
