In the DS9 episode Profit and Loss, Toran confronts Garak and persuades him to kill Natima and the others she came with, Garak seems to agree because he could be rewarded for doing so by Central Command.
TORAN: Then I don't suppose you'd be interested in going home again?
GARAK: Am I to be rewarded for informing the Central Command about the presence of Hogue and Rekelen on the station?
TORAN: Perhaps. But only after you see to it that they don't leave this station alive.
GARAK: And how do you propose to arrange this unfortunate incident?
TORAN: I'm sure you'll think of something. You always did in the past. Don't you see? Lang's death will benefit us both. Unless of course, you intend to spend the rest of your life as a tailor.
GARAK: I see your point.
TORAN: I knew you would.
In the end he kills Toran because he loves Cardassia.
Did he always plan to stop Toran, even if he didn't kill him? Or did he plan on killing Natima but changed his mind?
