Who’s responsible for Glenn’s death?
It would seem to be Negan.
Well, I’ll tell you who’s ultimately responsible:Robert Kirkman.

Kirkman is the guy who offed Glenn inissue 100 ofThe Walking Deadcomic book.
That set the precedent in the original source material.
Of course, the TV adaptation has transferred deaths before.
Tyreese was beheaded by the Governor in the comic book, but that became Hershel on the AMC show.
(A lot of good that did him!)
So it was kind of essential thatthat part of the sceneat least remained intact, unfortunately."
That’s not to say other outcomes were not considered, however.
“We did discuss options,” says Kirkman.
“Abraham died in the comic book before Cudlitz had ever been cast as Abraham.
Especially these days, just because you miss these people and it’s just not a fun process.
It’s tough but we gotta do what we gotta do.”
And now it is done.
