So, this is more of my frustration towards a "Upcoming death" 

This is pure spectulation so dont hold this against me if it ends up being true

Onwards, so I would be EXTREMELY angered if they were to Kill Merle Dixon, no matter what he does whether its a heroic death or not, they should keep him along for a while, I mean we haven't seen much interaction between Merle and Daryl, He isn't all to well developed he is almost T-dog 2.0. Why would they even bother making us wait 2 seasons to bring him back, and take almost 9 episodes to show us daryl and Merle meeting again, then kill him. 

TL;DR: Stop killing undeveloped characters AMC, it's frustrating and not entertaing.
