Luke, the protagonist, is like his Biblical counterpart. They are both Physicians, but Luke cures people by exterminating their enemies. He is an idealist, living in a pragmatic world - in otherwords, a misfit. Luke is a young virile man who needs to be taught about life and there are many who want to teach him. His Odyssey is sexual and violent. His sexual odyssey is not his doing but the murders are. And he argues with himself about their validity.
