take Arya's goal of revenge against those who have hurt her and those people she cares about. Cersei does the same. Arya is understood and praised or excused because of what she has been through while Cersei is condemned and made out to be an evil witch

but isn't the whole strategy of grrm? having us question what is right and wrong? what is honorable and dishonorable? these ladies taking revenge is a good example of the same action being taken by two different characters and because of our association with the character, we either condone it or attack it.
