I agree that Kahvi is just not in Winnowill's league at all. And I have never forgiven Winnowill-- again, because she has never shown remorse. I think for me that is the prerequisite for forgiveness. But I give Winnowill one thing-- if she's truly mad, she's not fully responsible for her actions.
If Kahvi wouldn't consider genocide because she just wouldn't, I can accept that. But I've always wondered if the difference wasn't simply that Kahvi never had the [i:5f865cae33]power[/i:5f865cae33] to do what Rayek did. If she'd had the kind of magic he has, how would she have used it? I wonder.
