There is a psychological defense called “identification with the aggressor.” If Person A swears and demeans, then Person B who is the object of these, begins to swear and to demean others. If Person B begins to forgive, do you think that would break the pattern of “identification with the aggressor”?
Yes, I do think that forgiving can break the pattern of identifying with the aggressor. Why? It is because as people forgive, then they see more clearly that what the other did was unfair, is unfair, and always will be unfair. Seeing this, those who forgive will not want to imitate those behaviors that now clearly are seen as unjust.
