5. Todd Alquist
Let's face it, Todd has had a bullet with his name on it ever since the tragic episode "Dead Freight" in which he cold bloodily gunned down an innocent child. The way Todd murdered the kid, almost without hesitation and his subsequent lack of remorse, has made him one of the show's biggest villains in recent episodes and it's fair to say there are more than a few of us who want to see him get his comeuppance. Todd looks set to be drawn into Breaking Bad's big finale following Walt's telephone call requesting him to ask his uncle and his Aryan Brotherhood connections to help him with the Jesse situation at the end of "Rabid Dog". And with Jesse wanting him dead ever since "Dead Freight", Jesse could end up getting his revenge by the show's end, something which would leave none of us shedding a tear.
