A permissive society is a society in which social norms become increasingly liberal, especially with regard to sexual freedom. This usually accompanies a change in what is considered deviant. While typically preserving the rule "do not harm others" (harm principle/non-aggression principle), a permissive society would have few other moral or legal codes (no victimless crimes, for example).
A permissive society ends up becoming quite deviant.
It allows for deviancy to exist, so a permissive society would become deviant in nature.  The system had trouble, because this is moreso inductive reasoning, which steps outside of a computers deductive reasoning skills.
