3. Omar Little (The Wire)
"You come at the King, you best not miss." Who wouldn't want to see Omar Little bring his own brand of vigilante justice to the streets of Kings Landing? He would have no tolerance for the Gold Cloaks killing infants in front of their mothers, or the knights of the Kingsguard striking the Kings bride to be. Omar would have also sought justice for the beheading of Eddard Stark. Imagine Joffrey sitting triumphant on the Iron Throne, only to suddenly hear the familiar whistling ... Kings Landing is no place for morals so Omar's strict code may work to his disadvantage, Would he endanger the lives of innocent children Tommen and Myrcella by outing Cersei and Jaime's affair? Ned Stark didn't want to take that chance and we all know how that turned out. And would he even be a good guy? Nobody on Game of Thrones is truly innocent so his "Don't hurt the innocent rule" really wouldn't apply. Starks, Lannisters and Targaryens alike would all be in the scope of Omar's shotgun.
