No be disagreeable all you like, good discussions are the only reason I am here, Just don't call me a idiot (which you may be thinking in this case because you are right, I forgot the Peach bit).
Stannis is prtrayed to be too strict and and concerned only with justice. It's almost like they want to show him as the Robocop of Westros, 100% by the rules regardless of what may be wrong or right or what his heart might want. That's why he isn't a villian, he honestly believes in the rightness of what he is doing. Davos is one of my favorite characters, he is sort of Stannis's conscious and heart. Davos is as much trying to save Stannis from himself as he is trying to save him from Melisandre. Stannis is so wrapped up in his right to be king that he almost misses the whole arguement that nobody else wants him to be king, and if it wasn't for Davos he would of never gotten it into his head that the problem is that nobody likes him, it was hard for him to understand that he was passed over for Renly because Renly had all the personallity. Now he is off to the North to do the right thing and prove that he should be King instead of bemoaning that 90% of the continent would be considered just as much of a traitor as his brother by his standards. The ends don't always justify the means, that is why he can't be judged a hero, he did things that were questionable and some that were downright wrong in order to push his claim to the throne. Renly was no more a traitor than everybody else who supported anybody but him as King, and instead of trying to convince people that they should support him he branded everybody a traitor for not doing so to start with. Once again a lot of that can be laid at Melisandre's feet. He is definatly not a evil character but he is equally not a heroic character, he is a character in flux between a raving madman who is only concerned about his claim to the throne, and a man who has the best interest of the Kingdom at heart.
