They're the sort of people who believe that there's always another way. Karol thought Estelle could use her position as the princess to punish Ragou in some way. But guys like that... they just don't learn. It doesn't matter what you do to them, they're always going to find a way to hurt innocent people.

If I could, I would've kept what I did from them. They might eventually understand what I was thinking, but it's not the sort of thing I want to force on them, you know? They're good people. They want to believe that there are ways to help everyone.
