7. Hm. I'd say that I'd want to marry someone who isn't a serial killer. Reasons being that if I'm a serial killer, I'm probably going to be a little unbalanced with lots of personality disorders, most of which include a lack of trust/inability to form healthy relationships, etc. So, even though I may love someone enough to marry them, I doubt I'm going to trust them fully. As such, if I were to marry someone who's a serial killer like me, I may fear that they'd turn on me and kill me. Plus, if I have someone who isn't a serial killer, they won't understand my work completely and I can get away with a lot more than if they understood how to outsmart me. (Sorry, that got long. :/ )

But. My blather aside, I sort of like the idea (in fiction, of course) of two serial killers hooking up. xP
