If I didn't know the end game of the Mayor I could see myself helping him out as a necessary evil.
Back when people were trying to get me to watch Buffy, more than one said I'd relate to Faith. As it turned out I didn't as Faith is way too impulsive, lusty, etc (not necessarily a bad thing in my book, but it's not me). Still, if I became more nihilistic (as a life of horror, violence, and death as Faith experienced might make me) then perhaps I could. But I'd have to give up on everything but the next moment. (I'm also generally not jealous as Faith was of Buffy. But then it seems everyone is prone to jealousy in the Jossverse, so maybe I would be there.)
