The Exorcist1973

Karras:
It's my mother, Tom. She's alone. I never should have left her. At least in New York, I'd be near, I'd be closer.

Tom:
Could see about a transfer, Damien.

Karras:
I need re-assignment, Tom. I want out of this job. It's wrong. It's no good.

Tom:
You're the best we've got.

Karras:
Yeah, not really. It's more than psychiatry, and you know that Tom. Some of their problems come down to faith, their vocation and meaning of their lives, and I can't cut it anymore. I need out. I'm unfit. I think I've lost my faith, Tom.
