If someone does us wrong or harms us should we then forgive him or her?

Forgiveness is a virtue, but the answer to this is not simple and dogmatic. We should do whatever prevents people repeating a wrong and do whatever is necessary to show them the error of their ways. If, for instance, someone robs or assaults us and we simply forgive and accept what has happened passively, then we are in fact encouraging the wrong that has been committed. We must either condone or condemn and an assault or a robbery is something which, in the interests of others and of society, is to be condemned. There is a difference between forgiveness and justice, and we must be wise enough to know the dividing line. Forgiveness must therefore be contingent upon certain things, but to be unforgiving is entirely wrong.
