Spare Margit, or let Niellen kill her?

[Elaini]

I did not let Niellen kill her in "Wild At Heart".

I did feel tempted to let him kill her, though. She's one of those people who really made my blood boil. It was suspicious to begin with that she didn't want Geralt to avenge her sister, and blamed Geralt as heartless for wanting to do so (what the...).

Then it turns out that she's the one who sacrificed her sister in order to get the werewolf to herself instead.

She needs to be sent to a mental ward asap. You can't get more insane than that. And you just don't do anything like that to your family members.

At least I saw her weeping in the hunter's hut after. It's the least that she deserves.

I let him have her....betrayed her own sister out of jealousy what a piece of garbage.
