Aang is a vegetarian, as shown in "The King of Omashu" (the 5th episode of first season) and "The Headband" (the 2nd episode of third season) when he refuses to eat meat since the Air Nomads taught him that life is holy. Aang states a reluctance to fight in "The Spirit World (Winter Solstice, Part 1)"; Aang hopelessly negotiates with a spirit who is destroying a village instead of fighting. Due to his non-violent nature, he also shows ethical reluctance refusing to killing Firelord Ozai, and eventually strips Ozai of his bending instead of killing him. In the show, Aang has a complex network of friends extending over all four nations.
