36. Xaro Xhoan Daxos
It's safe to assume the pretend-rich merchant who stole Daenerys' dragons died in that treasure vault she locked him in, considering its utter lack of food, water, or really anything. (Remember: he's only pretend rich.)
35. Brynden Tully
The artist also known as the "Blackfish" went down with honor -- or at least, we think he did. After Jaime Lannister took over his castle, Tully's death was staged offscreen, and presumably, he went down fighting.
34. Lord Roose Bolton
Roose Bolton was a bad man. He plotted against the Starks, killed Rob at the Red Wedding, and always had a disapproving look on his face. However, compared to his son Ramsay, Roose was a charming little imp and a model of steely pragmatism. It wasn't exactly upsetting to see him go, killed by his own son in the same brutal manner he eliminated Robb, but it did signal a power-shift in the North. He was the lesser of two evils -- which is probably why he couldn't survive for too long.
