Vengeance Feels Empty

A powerful plot element, pursuit of revenge may be a driving motivation for a character. It may even be central to the plot.

Upon finally exacting his revenge, rather than the sense of satisfaction, he may have expected and get nothing. Maybe, it wasn't really worth it or maybe he just doesn't know what to do with himself now and had nothing else to live for.

If they were avenging the death of a friend or loved one, they may realize that the deceased would not have approved or that it will not bring back that person and instead of blind rage, they now have to deal with actual grieving since rage may have helped them avoid it by putting the blame on their enemy.

This is one of the bad results of ignoring Forgiveness. This is because a person who chooses the path of revenge has condemned a part of their spirit to be stuck in the past and eventually destroyed which ends up making them worse off than before when the object of their revenge is destroyed by their hands and they feel little to no satisfaction after doing so.
