Star Trek: Deep Space Nine, Season 4

Tora Ziyal:
You don't like my father very much, do you?

Kira Nerys:
No, I don't.

Tora Ziyal:
I understand. He did some very bad things during the Occupation.

Kira Nerys:
Yes, he did.

Tora Ziyal:
It bothers him, you know?

Kira Nerys:
[Disbelieving] Does it?

Tora Ziyal:
Very much. He talks about it sometimes. He'd never admit it to anyone else, but he thinks the Occupation was a mistake.

Kira Nerys:
Somehow, I don't think he'd say that if the Cardassians had won.

Tora Ziyal:
Maybe not, but maybe losing made him a better person.

Kira Nerys:
Well, then, a lot of innocent people died for his education.
