8. Rickon Stark

When it was first revealed that Rickon was delivered to Ramsay by Smalljon Umber, we had some hope. But he essentially returned to the show to die. Ramsay's sadistic way of murdering him was mind-blowingly awful for viewers and for Jon Snow, who saw it up close.

Time of death: Season 6, episode 9, "Battle of the Bastards"

Cause of death: Ramsay Bolton shot an arrow in his back, while pretending to give him to Jon Snow unscathed.
