Weiss: All that’s ever mattered to Cersei is her children and in relatively short order, Cersei has lost all of her children. She now is in a very dark place and all she really has left is power, for the sake of power.

Weiss: Jaime really wants her to engage with what’s happened to them both and these are things that she can’t afford to even entertain really because if she starts going there, it’s gonna be a long-long fall.
Benioff: For her now, at this point, it’s about survival and the only way to survive is to defeat her enemy. She’ll do whatever she has to do to win.

She’s capable of anything, unlike Daenerys, who is constrained a little bit by her morality and her fear of hurting innocents.
