Love and forgiveness cannot be dominant values absent a clear understanding of principles of justice, right and wrong.
If someone steals something, say a prized painting, the thief has accrued a debt. Justice demands that the painting is returned to the owner. Forgiveness and love both support returning the painting or, at least, the return of something of proportionate value. There is no sense in saying the thief stole the painting but it’s okay we all love and forgive him and he can keep the painting he stole. There is something very wrong with that view of the wrong committed. The victim whose painting was stolen should get it back. Love actually demands it and forgiveness is totally contingent upon that return.
When someone takes another person’s life from them unjustly, they are taking EVERYTHING away from the murdered victim. What possible recompense can the murderer make to return life to the dead person? Clearly none can be made. That, however, doesn’t justify us survivors in saying, “Well, that’s that. The murderer can just walk away. We forgive and love him. The deceased is dead anyway and he won’t miss his life. He isn’t even aware of having lost his life. Debt forgiven, nothing owed, let’s all go on our merry way and forget the whole sordid thing.”
Seems to me there is something very wrong with that view, even if we decide to jail the perpetrator merely to keep others safe from the murderer.
What is missing is that the murderer owes a great debt, and justice (and God) demands a repayment. That repayment cannot be dismissed as mere “seeking vengeance.” Someone has lost the most precious possession they could possibly have, their very existence. I suspect God does require repayment in full. And we have no right to devalue the victim’s life by dismissing it from all our moralizing and accounting.
A proportionate repayment would be that the murderer forfeit his life and do so without reserve IF he truly does subscribe to proper principles of justice, is taking full responsibility for his action, and is seriously trying to make things right with God. Now God may not take him up on that debt if God sees something to be gained (future good acts that the guilty party might do to offset his debt) and God may even let the murderer off with a less than full repayment, but that does not deny the fact that the proper and just repayment of the debt that a murderer should owe is forfeiture of his life. And if more than one life was taken, the debt goes beyond the possibility of repayment.
