Though, of course, none of them are good. With all the others, there is some sort of motivation, something other than the simple desire to kill those that wronged her. Arya's sole goal in life is the extermination of a well-determined list of people that have commited offense upon her in her life. I do not see how this is good in any way or sense. And her shortness and likeablity are not at all justification for her sins. She has taken steps to accomplish her evil goal through evil means. Consorting with assasins and later joining a guild of them so she can become one herself. The people on her list have wronged her, but many of them have not done it in such a life threatening way that their deaths can be justified.

Robert Baratheon is certainly presented as "good" in the first book. He is likeable and friendly, if he has changed from the man he was, we get many favorable POV scenes from Ned's perspective. However, when you look closer at his actions, he is a very bad man, if not as evil as Arya or Cersei. He led a revolution against the annointed King for a stolen love. Though many houses supported him not because of love but because of the weakness of the Targaryens, and because the Mad King was truly a threat to the realm and it would better many people's lives to have him gone, Robert's sole motivation in leading a rebellion was that his betrothed fell in love with another man. Seems like an awful reason to kill so many to me. And then, years later, he demands sending assasins to do away with the last remaining Targaryens. A pregnent 14 year old girl. Though it is possible that he desired this for the purposes of eliminating rallying points for future rebellion, it is fairly clear from what we know about him that he is doing it for his personal hatred of the family. This puts him up there with Madame Defarge for EVILNESS.

I am not defending Cersei when I say that she is less evil than Arya and Theon. Whether or not you call it POV trap, she has some justification for her actions. She, like Cat Stark, does everything she does for her children. However, unlike Cat Stark, she has ambition far above what would be accepted for a woman in this world and a desire to promote some convuluted form of gender equality by getting herself power. Of course, her methods are definitely evil, but she views this as only doing what she has to do to protect her children and her house. However, as of AFFC when we finally get her point of view, I am of the opinion that she is really mentally ill at this point, so she is not responsible for her actions and cannot be classed as evil.

Theon is a bad dude.

Jaime isn't.

If you need explanation, I posted it on the quickpoll a while ago.......
