My girlfriend and I can’t remember the name of this movie. It was low budget, with no big names in the cast. Mental patient claims to be an alien with supernatural powers and takes an interest in the lives of other patients. There is an evil nurse who murders people, and the main character grows particularly close to a young woman who was abused by family (or something). Eventually, after he learns about the cruelty and evil of people, it is revealed that he is the son of Jesus. Jesus appears and tells him that this cruelty is why he turned his back on humanity.
