Which would be a BIG mistake IMO. And I'm not only saying that because he's my favorite. I just thing he adds another element to the show, instead of the other cookie-cutter characterizations.
There are just so many different angles you could do. Have him go full on "villian" if you want; have the group fracture and some go with Rick, some with Shane, etc.
Love him or hate him, you have to admit Shane is a good character. It would be a waste to kill him just because the majority of the viewers dislike him and his actions.
it was written in the stars for him.
