The emotional opposite of resentment is forgiveness. However, forgiveness does not mean condoning or overlooking the offense. It does not mean reconciling with someone who has hurt you. Neither does it require that you forego legal procedures of justice.
Forgiveness means letting go of the compulsion to punish, in the realization that we cannot harm others, particularly those we love or have loved, without harming the self.
