4. Craster
Any guy who finds his own daughter sexually attractive should probably have his head knocked a full three-sixty around a few times and put away. Craster takes the show's characters to a new level of degenerate as he marries each of own daughters, referring to them all as his wives. These wives produce more children, who in turn become his next wives and so on. All of his hapless daughter/wives live with him North of the Wall where he is visited time and again by the forlorn men of the Night's Watch. The Lord Commander puts up with Caster's depravity in the show (remember number eight about all crows needing a smack?) in turn for food and shelter. That is, of course, until Craster's holier-than-thou attitude gets him stuck with a sword through the back from one of the Watch's more nefarious creatures. Craster goes down, blood and steel, shouting his righteousness and in a sickening way that he's not being a hypocrite. For every daughter he forces to become his new bride he has a son that he sacrifices to the white walkers out of jealousy, thinking that one day they will grow and steal one of his wives. His wives also known as his son's mothers/sisters/aunts.
