It might turn me on,depending on the circumstances, if she was fukking dead bodies or keeping body parts in the fridge to eat or some fukked up shyt I draw the line at that, but it would be kind of hot to know your woman is in actual fact a psychopath who has your back in any situation. I wouldn't stay with a severely mentally ill woman, too much drama as she couldn't control her urges and violence,too unpredictable , but a psychopath maybe.It would also depend just who she was killing as well. Kids I would go to the police myself and shop her.
