19. Stannis Burns His Daughter Alive
Season 5, Episode 9: "The Dance of Dragons"
Sadly for Stannis, the good vibes couldn't last forever. Baratheon's rescue of the Night's Watch and his decision to retake the ancestral Stark home from those who stole it made him seem like a decent guy. But when the going got tough, the man who would be king decided to sacrifice a princess, hoping that burning his disfigured daughter Shireen alive would please the Lord of Light. Instead, his wife committed suicide, half his army deserted him, and his offspring died in agony – all so that he could get his ass kicked by mad Ramsay Bolton and get beheaded by Brienne of Tarth. Grotesque in its own right, the killing of the child was also a total waste. While the murder hasn't yet occurred in the books, one can only imagine how horrifying it'll be in Martin's hands.
