'The Walking Dead'
Daryl vs. Merle (Season Three, Episode 14: "This Sorrowful Life")
The Walking Dead takes many of its most memorable characters and shocking twists from its source material, the comic of the same name by producer Robert Kirkman and artists Tony Moore and Charlie Adlard. Daryl and Merle are different: These rough-hewn redneck brothers are the TV show's original creations, as well as its breakout stars. So when Daryl was forced to put his zombified older brother Merle down, it was a heartbreak no one could see coming.
