No. 3 Joffrey Baratheon
TV Series: Game of Thrones
Portrayed by: Jack Gleeson
This character is so hated among Game of Thrones fans that it’s irrelevant to explain why. He is the son of the nearly-equally reviled Queen Cersei, and enjoys killing and torturing innocent people from peasants to his own betrothed Sansa Stark; all to protect his pride, and get his medieval jollies.
