The murderer owes a debt both to the individuals directly affected by his act and to society as well.
What he has taken away cannot be returned no matter how much pain is dealt to him.
The Church speaks of “redressing the disorder” caused by the crime and this can only be accomplished by assigning a punishment commensurate with the severity of the crime.
In other words, the ol’ “eye for an eye” principle. It’s attractive to many people, especially six-year old children on playgrounds. You stole my toy, so I’ll steal your toy. You punched me in the back, so I’ll punch you in the back. Fighting fire with fire sure solves a lot of problems, doesn’t it?
What your Church is advocating is an option for people to get revenge via the death penalty. Revenge is a childish and base notion however you look at it.
Nothing will bring the dead back to life but that is no argument for not applying the punishment the crime deserves.
But it is an argument against the concept of “deserving.” This whole debate is essentially character ethics vs. consequentialist ethics, so our disagreement is actually a profound one, running back to the fundamentals of our ethical systems.
The Church views morality with the goal of attaining perfect character in mind, which obviously requires a model for us to measure our characters against. God is supposedly the ideal character, and his actions are exempted from the scrutiny of the faithful. But this begs the question: How is it that God’s character is ideal? The goodness of God’s character is then declared axiomatic.
But this is nonsense, and we both know it. We derive our conception of “good character” from the consequences of actions. Being honest makes for good character, for example, because acting honestly tends to produce better consequences than acting to deceive does. Being a peaceful person is better than being a violent person for similar reasons. People who tote character about as the Church does then create virtues to assure that these positive qualities will be upheld by the public, but these qualities are only deemed “good” because of their consequences. Virtue ethics only has a leg to stand on because of consequentialism.
That may not be the purpose of prison but it is surely the principle purpose of punishment.
Tell that to the six-year olds on the playground who are…umm…“successfully solving their problems” by hitting and stealing from each other. Prevention of harm and rehabilitation are the only ways to go.
