Commander William Adama: I've asked you here to find out why the Cylons hate us so much.
Sharon Valerii: I'm not sure I know how to answer that. I mean, hate might not be the right word.
Adama: I don't want to fence with you. I just want to know why.
Valerii: It's what you said at the ceremony before the attack when Galactica was being decommissioned. You gave a speech that sounded like it wasn't the one you prepared. You said that humanity was a flawed creation. And that people still kill one another for petty jealousy and greed. You said that humanity never asked itself why it deserved to survive. Maybe you don't.
