Moral Event Horizon: Fred, when he decides to kidnap a 15-year-old girl, take her to Mexico and rape her, and (it's implied) prostitute her.
Values Dissonance: The handling of Serafina. At the time the film was made it's very likely she wouldn't be viewed as in need of psychiatric help, and authorities would have been content with allowing an institution like Girl's Town to handle her. Today she would almost certainly be recognized as a danger to herself and (likely, given her jealous fit at the party) others, and would likely be remanded to a mental health professional.
