Some people blame Sansa for Ned's death, and some blame Ned for his own death. Imho, Ned dug his own grave by going to Cersei. Still, in an interview GRRM said, "Sansa was the least sympathetic of the Starks in the first book; she has become more sympathetic, partly because she comes to accept responsibility for her part in her father's death." Does this mean her actions really did contribute to his death? The interview was done by Amazon UK. I believe you've linked it in a post before. Thanks!
