I do not think they will kill off Daryl. Of course they are going to say "nobody is safe" because they want us to be on the edge of our seats thinking "will they?" I do think the show would suffer, he has an unbelievable following. I think the truly safe ones are: Rick, Daryl, Carl, Carol, Glenn, Maggie and Michonne. Judith as well, but I don't really see her as a big character, she is almost like a prop. I think some others are gaining popularity as well and they need to either kill them off before they become "untouchable" or add them to the list of safe characters. Those are: Sasha, Abraham, Tara and Eugene. I think Rosita will go soon, she adds nothing.
