Damien Karras

Father Karras was one of the priests who exorcises the demon from young Regan MacNeil. He is a Jesuit psychiatrist suffering a crisis of faith. He searches for proof to lead an exorcism, yet during his investigation he comes to realize that there is no better way for God to prove His own existence than to reveal the foul presence of a demon. During the exorcism, the demon frequently brings up the subject of Karras's mother's death and how he wasn't there to see her die, which seems to trouble Karras emotionally.
