[Avatar: The Last Airbender] Why did the Dai Li betray the Earth Kingdom?
gpt
The Dai Li were never for the Earth Kingdom in the first place....they were only interested in holding and retaining power for themselves, to the point where the Earth King was their puppet. Azula’s infiltration of Ba Sing Se made them realize they could no longer hold off the Fire Nation, but she convinced them that they would continue to rule the Earth Kingdom as a client state of the Fire Nation. Basically like the Vichy regime.
