You know....when it comes down to it, none of the villains from FFIX were evil. I mean certainly they were very much the opposite of good, but not trully evil.

Garland was just doing what he had to to keep Terra alive. Sure his actions were unjust to the rest of the world, but so what?

Brahne was just greedy. She was manipulated by Kuja. Her insides were empy and she wished to fill the gap, by being the ruler of everything.

Kuja just did what he was raised to do. Destroy. Sure, he did wish to conquer the world, but it was only in his nature, because he thought that being ruler of the world would prove that he was not some lowly creature created for a small,insignificent task.
