Elijah/Klaus
Because it never stops, Niklaus. The hunger never stops. The first time I ran into a person after I turned, I killed them. They did nothing wrong outside of being at the apartment at the wrong time. Ezio took care of the body for me. Then I almost killed him. Luckily I didn't. Everything is enhanced. Especially emotions. Even with all that aside, I don't want to live forever. I just...want to live. I want the experience of getting older with someone. Not being stagnant.
We are more powerful, yes, but I don't know. I'd be happy enough to be human. I doubt it will ever happen, but I would be. At least I believe so.
