I'm well aware that no character can be considered fully good or evil in the Game of Thrones universe.
However, the show tends to make us hate or love some characters based on the morality or dishonor in their acts. At least that's my impression.
This good or evil "tag" on every character can change during the story, like with Jaime (and I hope with Sansa in the future). But it's rather stable in time.
So let's call a "good" character one that has been acting morally or with honor at least for some time.
Now are there exemples of duels where two "good" characters had to fight each other? The emotional effect would be particularly interesting. The only cases I can think of are:
- Brienne vs the Hound for Arya's protection
- Brienne vs Loras in Renly's honor
- Beric vs the Hound as noted by TLP in comments.
nobody really died in these cases.
Examples from books are welcome!
