Martin is a fan of history and one thing that becomes apparent when you read historical events is how often the 'good' guys don't win. That is the exact opposite message that Hollywood would have us believe. In most movies, the good guy is honorable and eventually overcomes all obstacles. In Game of Thrones a character can do everything that the viewer believes is right and still die or have something terrible happen to them.
Martin said that his stories are about struggle and you can see that in how much hell certain characters have to overcome. Also, Martin seems to understand that most people, even those who do horrible things, believe that they are good. I don't think that any of his characters believe that they are bad so when you read a chapter from their point of view you get to see their reasoning for their actions. I do think that the morals of Game of Thrones are subjective, for the most part. Martin is very good at creating complex characters who are neither good nor bad or if they are bad, also do good things.
