WellI figured if you make a human who actually WANTS to fight the vampires, that he/she is a crazy mother fucker and may be shunned by other people in the community. He/she could possibly have some dirty laundry, if you know what I mean. Something that has messed him/her up in the head. ORRRRRyou could make he/she really cocky and just want to show out the diablerie and show that humans are better and can fight themselves, ORRRRRRRR you can make a super fan of the Diablerie o - o
