Stop that. A "witch" thing? Kimihiro. Those are thoughts that everyone has, sometimes. When you really really hurt, everyone wants other people to hurt like they do, to know your pain as you lived it. That darkness dwells in every single living thing. Anyone who says otherwise is lying. Whether you act on it, or if it's just a fleeting and intrusive thought that worms its way into you mind... it doesn't matter. It doesn't make you less of a person. And it doesn't mean you've totally severed your bond with him.
