I'm totally late here, but I'm pro Carl shooting Jody. And not just because of the sketchy way he was handing his gun to him after he was asked to drop it. First, Carl was with a disabled old man, a young gal who ain't been doing much, and an infant. Second, this kid just stormed the prison to kill them. He had no way of knowing the Governor would mow every one down anyway, so all he was presented with was someone who came to kill them fleeing to presumably go back to Woodbury to regroup and come back again.
And Rick can't say **** to him. He only then discovered "Hey, maybe we should save people like we used to.." and Carl was with him when they drove passed a lone man begging them to save him, only leaving him to die.
Milton broke my heart. I wanted him to live. In my finale he made it to the prison where Herschel showed him his leg and they all lived happily ever after. Her name escapes me now (Dr. Andrews?) but I thought he would fill her position from the comic.
