Darebin refers to himself as Half-human rather than Half-orc, because he wants to challenge the assumptions of other races who see his Orc side and assume the worst, while he has witnessed many and worse atrocities committed by the hands of humans than any other race. Darebin believes Orcs live a life of savagery only because they have not been allowed to share the benefits, privileges and responsibilities of a civilised life. Darebin lives his own life as an example for others.
Darebin will never use lethal combat against another Orc or Half-orc. Instead, he will use unarmed non-lethal combat to knock his foe out, but spare his life.
