It would be far more constructive if people tried to understand their supposed enemies. Learning to forgive is much more useful than merely picking up a "stone" and throwing it at the object of one's anger, the more so when the provocation is extreme. For it is under the greatest adversity that there exists the greatest potential for doing good, both for oneself and others.
True forgiveness always has a sacrificial character. It can never have a passive character. For we do not simply make a decision to "forget" the wrong or injustice that has been perpetrated upon us but, in addition, we take upon ourselves an inner obligation to MAKE AMENDS for the objective harm which evil action has wrought not only upon us but also upon the world. In true forgiveness we willingly, out of complete inner freedom, take upon ourselves an inner obligation to give the world as much compassion, love, and goodness as the evil action has objectively taken away from it.
