Abuse of trust is a term used to describe a situation in which someone takes advantage of another person's trust or confidence for their own gain. Betrayal is a form of abuse of trust, where one person deliberately breaks the trust of another by acting in a way that goes against the expectations of the trusting party. This can be done through deception, manipulation, or other forms of dishonesty. Abuse of trust can have serious consequences, including financial loss, emotional distress, and even legal repercussions.
