5. Robb Stark

Easy on the eyes and a man with almost as much honor as his father, Robb really did himself in when he broke his promise to marry one of Walder Frey's daughters and married Talia instead.

Time of death: Season 3, episode 9, "The Rains of Castamere"

Cause of death: Shot with an arrow by a Frey, then Roose Bolton stabbed him in the heart.

Sadness ranking: 9. Robb was one of the few characters left to root for in the War of the Five Kings, and his death was particularly brutal, especially seeing his corpse paraded around with his direwolf's head on top.
