Forgiveness is the intentional and voluntary process by which a victim undergoes a change in feelings and attitude regarding an offense, lets go of negative emotions such as vengefulness, with an increased ability to wish the offender well. Forgiveness is different from condoning (failing to see the action as wrong and in need of forgiveness), excusing (not holding the offender as responsible for the action), forgetting (removing awareness of the offense from consciousness), pardoning (granted for an acknowledged offense by a representative of society, such as a judge), and reconciliation (restoration of a relationship).
