Aang & Sokka in Avatar: the Last Airbender - The Runaway
Zuko was having a crisis for three weeks after joining the Gaang, because he realizes a) Katara, Aang and Sokka could have and would have easily murdered him had they been about 5% more emotionally unstable and b) he had stopped actively trying to capture the Avatar right before the person who had no such qualms about murder, Toph, joined their team.
remember when katara wanted to blow up a factory for Environmental Justice and aang just tagged along because he thought it would be fun to be an ecoterrorist
