StarCraft: Brood War1998

[Kerrigan has betrayed Mengsk by killing Duke and his forces]

Arcturus Mengsk:
Kerrigan, you murdering b*tch! We had a deal.

Kerrigan:
Oh, come on, Arcturus. Did you really think that I would allow you to come into power again? You practically fed me to Zerg on Tarsonis, you're directly responsible for the hell I've been through. Did you honestly think that I would let you get away with that?

Arcturus Mengsk:
But you said revenge was secondary to defeating the UED!

Kerrigan:
I lied. I Liberated this planet because it was the UED's primary staging point, not because I was under any obligation to you. I used you to destroy the Psi Disrupter and now that I've got my broods back, you're no longer necessary for my plans. I think I'll leave you here, Arcturus, among the ashes of your precious Dominion. I want you to live to see me rise to power and I want you to always remember, in your most private moments, that it was you who let me loose in the first place
