Is it possible to forgive too much? If so, what would that look like?
Can you be too fair with people? In other words, is there a situation in which the practice of justice can be too much? I do not think so because all of the moral virtues are good and so the practice of the virtues also is good. What you might have in mind is what we call false-forgiveness. In such a case, people, for example, are continually trying to put on a show of their own high virtue and so they are insincere. Also, if someone distorts forgiving by isolating it so that no justice occurs along with forgiveness, then an unhealthy and hasty reconciliation might occur. So, if the forgiving is genuine and is balanced with justice, then there is no such thing as too much forgiving.
