Damon

Vessel to the fallen angel Berith, Damon mostly remains dormant as Berith uses his body. He has no love for the angel, forcing him out when he can and sitting in baths of holy water to make it as painful as possible when he returns. He suffered intense abuse as a child and it left him apathetic and bitter, and signed over use of his body in exchange for revenge against his abusers. 

He feels no regret for his choices and has very little self preservation, knowing that whatever trouble he gets into, Berith will bail him out. If he witnesses someone doing something he finds disgusting (usually things relating to his own trauma), he'll kill them immediately and without remorse.
