"What does matter, then, if not your own fate?" he asks, also maintaining a calm face and voice. For despite his anger, he is always one who wants to know why things are the way they are, and he will put aside other ends momentarily or sometimes permanently, to follow that curiosity.

"I beg to differ with you, though. What happens here matters very much, even if people can come back from death. Most here are mortals, who experience their own dissolution as an incomparable horror. Coming back out of that oblivion is not much better; it is also a traumatic experience, except for the reunion with their loved ones. I do not want anyone I care for subjected to that. They do not have a large enough perspective to weather it well, even if you and I do. And it is true that your Vrocks did not succeed in killing me; instead, they themselves died. But I am not angry on my own account, rather on Margaery's. And on the account of anyone else you might choose to target in the future."

Oh yes, he's stubborn. They have that in common. But she may bide her time as she will, it will not avail her.
