Betrayal, as a form of deception or dismissal of prior presumptions, is the breaking or violation of a presumptive social contract (trust, or confidence) that produces moral and psychological conflict within a relationship amongst individuals, between organizations or between individuals and organizations. Often betrayal is the act of supporting a rival group, or it is a complete break from previously decided upon or presumed norms by one party from the others.Defining "betrayal"Rodger
