I guess what really annoyed me is that Carl’s death is now more significant than Glen’s death. At least that is how I see it. Rick is allowing Carl’s letters to become almost “biblical” in nature and negating Glen’s death. I see it as truly selfish on Rick’s part.
I think you are right.
I do agree with Carl that there has to be something “after”. But to me, the answer would be capital punishment for Neegan, and some kind of probationary period for all of his minions.
Putting Neegan in a cell for the rest of his life is just a waste of people (guards) and resources. In addition, it gives him the opportunity to escape later on. After all of the harm that he’s done to so many people, that’s too big a risk, IMO.
