11. Margery Tyrell

Margery started the series as the wife of Renly Baratheon, but quickly joined the Lannisters in an attempt to get the Tyrells a seat on the Iron Throne after his death. At first she came across as self-interested, but the kindness she extended toward Sansa Stark and the poor people of King's Landing proved that while she was a master manipulator on the same level as Cersei, she had a good heart.

Time of death: Season 6, episode 10, "The Winds of Winter"

Cause of death: Burned alive in Cersei's wildfire explosion at the Sept of Baelor.

Sadness ranking: 8. Margery saw right through Cersei and would have been a good ruler, especially with the help of her grandmother, Olenna Tyrell. Her death was very unexpected and it was sad to see another character to root for go.
