[sansa laughs a little, both because that's the kind of stupid thing sandor clegane would probably say and because 'how do we keep the undead lich emperor from respawning' has become a topic of conversation around trench. she looses more thread as they walk.]

Well, they don't always come back, but it does seem to me that the ones you want to stay in the ocean never do. [definitely biased here] Anyway, it's good to be careful; The Reckoning comes every year, and she'll kill you if she thinks you've done murder, even if someone else might say it was justified. And any bloodshed here just adds to the blood pollution, which poisons the soil and turns people into Beasts. Besides, you always have to mind your own corruption, which comes from any kind of trauma just as much as it does from blood pollution. Corruption poisons your mind until you can't even recognize yourself. I've never met anyone who didn't regret what they did while they were corrupted, or a beast especially.
