Aside from Arya, Brienne, the Dragons, the Hound, Tyrion, Varys, and Jon Snow; Everyone I have liked in the books are dead. I liked Eddard Stark, he died; I liked Khal Drogo, he died; most of the other characters I don't care for and would to like to see die: Cersei (Definitely), Littlefinger (must happen soon!), Sansa (Stupid to believe in fairy stories and apply them to Joffrey and never suffered enough), other characters who should burn in dragon fire.
I am more looking forward to the Others nearly killing everybody before the dragons show up to burn them to death. I really don't want to see more than a few people survive as I think it would just reinforce the message of the books which happens to be simply "Be a complete and utter jerky piece of crap survive; be decent even slightly, die like a dog or just die somehow". The terrible villains keep winning in the books, I don't care for that. If we can't have a decent person surviving to the end, then kill off everybody, it will better that way.
