6. Tyreese's Decapitation
Tyreese get captured while trying to save his friends. The Governor tries to use him in order to take over the prison. Rick, though, won't let him in. The Governor decapitates Tyreese with Michonne's sword as a result.
Why We Won't See It: For the hundredth time, Tyreese hasn't been introduced. Introducing him now, but then killing him a couple of episodes later would be pointless.
How We Could See It: It doesn't have to be the Governor who does it. Another psychotic character can be introduced later on in the show.
5. Kids Decapitated
I don't want to place a photo of decapitated kids here. The survivors have found a home in the prison, but 4 prisoners have also. One of them is really a psychopath killer and murders Hershel's children. Rick nearly beats the killer to death out of uncontrollable rage.
Why We Won't See It: Herschel's children, Rachel and Susie, were never introduced in the show. Killing kids off, especially by decapitation, would not sit well with many of the show's viewers.
How We Could See It: There is no way we will ever see this on the show.
