6. Glenn Rhee
It says something about how beloved Glenn is that his death at the start of Season Seven has been the last straw for many TWD fans, several of whom have stopped watching the show because of it – even though what happened to the character on TV was taken directly from the comics. Prior to his murder, the ever-upbeat ex-delivery man had been in the series as long as Rick, and though he'd seemed to be dead multiple times before, our man Glenn somehow persevered each and every time ... except the last time. His final fate appears to mark a turning point in the plot, signaling the end of the survivor's can-do spirit and the dawn of despair. For many, Steven Yuen's character was the heart and soul of the show. R.I.P.
