Micah (Jake Weber) was the founder and former leader of the religious cult Korban. He was the husband of Julia, who acts as the head of organization for the community. His desire, upon Joe Carroll joining his flock, is to expand his cult by becoming infamous – in ways that he references several killers (Charles Manson being the most prominent) and wished to begin “killing people” to make his group known.  After following Joe and taking his advice for his dreams, he is killed by Joe to take control of his cult and make it his own.
