Forgiveness and mercy are letting bygones be bygones. They are granting pardon to those who have done wrong, accepting the shortcomings of others, giving people a second chance, and not being vengeful. Forgiveness is the character strength that undoes hatred. It can be defined as the removal or cancellation of a transgression or debt so that a transgressor becomes a candidate for a restored relationship with the offended party.
Forgiveness is separate from the concept of reconciliation, which is the restoration of the broken relationship and involves the restoration of trust. However, with forgiveness, the psychological responses to the transgressor and transgression become more positive or benevolent.
