I don't think they'd kill Daryl off. He's got too many adoring fangirls. And we all know what happens when fangirls get mad. Much blood is shed.
I'm a fanboy. So looks like next they are going to a prison. Heard about it in the comics and saw it at the end of Season 2. T Dog better step it up and they better kill off Carol. Carol and Lori are just useless. Carl should become more of a man like in the comics, but can't be sure they will do that.
