Famous Robert McAfee Brown Quote
...That we must never forgive would seem to follow from the same stern logic. For if we forgive, it will be a sign to those in the future that they can act without fear of punishment, and that the world has a moral escape valve labeled 'forgiveness' that permits evil not only to survive but to thrive...Forgiveness becomes a 'weak' virtue, one that Christians seem particularly prone to champion, and one that always carries the possibility of condoning, rather than constricting, the spread of evil.
