I'm not sure it's that simple. There's no guarantee I'd get the same soul, necessarily. A soul you get as a curse and one you get as a reward are probably pretty different. Besides, as long as I don't sleep with Buffy, this one's not going anywhere. Maybe if I thought she was ready for a relationship with me, but she's made it clear that she's not.
When you say you have no control over what happens when he's in the room -- is he able to hypnotize you? Only a few vampires in my dimension who can do that. Does he have this power over everyone or just you? I'm pretty sure I'd be immune, but it's something to be aware of.
Yeah, the hunger can be a bitch. Although ice cream tastes amazing when your taste buds work for foods other than blood. I've heard.
A normal life is a pretty good thing to aspire to. I used to want one myself, but now... I know I can do more good this way. I'd rather help people like you get the lives they want. So this Klaus guy, is he using the magic that lets vampires from your dimension go out in the sun? Or should I wait until nightfall to go out hunting for him? If the sun here gives me the option, that is.
