That kid Olly thought he was doing a good thing by shooting an arrow in Ygritte's back, but all he did was break Jon Snow's heart. AND OURS.
22. Tommen Baratheon
Poor, sweet, simpering Tommen was never long for Martin's world of chaos, betrayal, and verdant explosions, but nonetheless Messrs. Benioff, Weiss, and Sapochnik handled his passing with such a deft touch, it doesn't matter. The crushing silence of his suicide -- and the meme-worthy GIFs that followed -- produced probably the most memorable isolated death in "The Winds of Winter," an episode with the highest main-cast-member kill count of the the whole series since "The Rains of Castamere." One question nags at us: where is his trusty cat, Ser Pounce?
21. Walder Frey
Old Walder had to die, and it had to hurt. If Game of Thrones is a show about betrayal, it's also a show about consequences. For all his deconstructive tendencies in the early seasons of the series, Martin's views on predetermined retribution have revealed themselves to be pretty standard five seasons after Ned Stark's head was first lopped off. So Frey had to die. The things that didn't have to happen are what make his death great, specifically: the cold symmetry of Frey's slit throat and Catelyn Stark's, baking Frey's kids into a pie, and most triumphantly Arya doing the deed herself.
20. Night King
A leap, a catch, a stealthy knife drop, and the biggest threat to Westeros that ever was was taken out in a shower of ice crystals. Arya proved herself to be the hero the world deserved when she iced the Night King, and in a matter of moments the Army of the Dead vanished from the face of the earth forever.
19. Khal Drogo
When the series started, Drogo wasn't an easy guy to like. But thanks to his relationship with Daenerys and one hell of a performance from Jason Momoa, everyone came around on the Khal. So, naturally, that meant it was time for him to die. First came infection, then black magic, and finally, the pillow-smothering. By the end, it was hard to disagree with Daenerys' mercy-killing decision. But damn if we don't miss this guy's bluster.
18. Lord Ramsay Bolton
Ramsay's death was an event we anticipated, imagined, and rooted for with varying levels of intensity. Basically, he had to go. After seasons of watching the Bastard of Bolton murder, rape, torture, flay, and humiliate beloved characters, it was poetic -- and yes, disturbing as hell -- to watch him get devoured by his own dogs, the beasts he starved to terrorize others. But who do we hate on now?
17. Theon Greyjoy
Having finally redeemed himself in his family's eyes by saving his sister, Yara, Theon was ready for any challenge the world could throw at him, even if it was a death trap. He died protecting Bran, the foster brother he'd once pretended to murder.
