Kaya certainly didn't respect this decision. She felt betrayed by the Council, by the people on it who she thought might actually care about their opinion, who would try to spew some nonsense about giving Azula a second chance! Why, because she didn't succeed the first time?

There was point in arguing about it now, not when these jerks had already given their say so. It sickened her to know she had voted for this, and now Azula would be on the ship, walking around. Without even so much as asking anyone who knew what she was

And forget just her as a threat...Mai might kill her, and what would that do to Zuko? So she kept quiet now, her fury evident in her expression.
