In Book XV, Aristotle gives four criteria for good characters:
1. Goodness
2. Propriety
3. True to life
4. Consistent
The main characters (Ang and allies) are morally good. Out of the many different themes and messages of the Avatar series, the one that most thoroughly pervades the show is balance. Not between good and evil (which is an insidious philosophy) but between goods. This chord truly strikes harmonious with the teachings of Aristotle.
