He was the moral compass of the group and it’s always good to lose the moral compass. It will all become clear when we finally show you the back half of season 4. It wasn’t enough for these characters to lose the prison. They also had to feel some kind of loss over something important and Hershel was that thing that was important to each and every character, so it made the most sense to take him off the table and see how it affects the characters, which we’ll see when we come back in a bit. So there’s a lot of cool stuff ahead because of that.
