The second edition of the catechism has really muddled what the church teaches about punishment in general and capital punishment in particular. You would not learn it from the section you cited but punishment has four objectives:Punishment is held to have a variety of ends that may conveniently be reduced to the following four: rehabilitation, defense against the criminal, deterrence, and retribution. (Cardinal Dulles)
And while it is not immediately obvious, 2266 identifies which objective is primary:* The primary scope of the penalty is to redress the disorder* caused by the offense.
That is - and this is the hard part for most people to accept - the primary objective of all punishment is retribution (retributive justice). The USCCB, which is generally unhelpful in most things, actually provided some clarification on this point:*The third justifying purpose for punishment is **retribution ***or the restoration of the order of justice which has been violated by the action of the criminal. We grant that the need for retribution does indeed justify punishment. (1980)
The “order of justice” they refer to is the same as the “disorder” the catechism identifies and by this is meant a good deal more than simply “law and order.” (The “third justifying purpose” does not mean third in importance but merely the third objective they addressed in their unordered list.) Aquinas (of course) is more specific:the act of sin makes man deserving of punishment, in so far as he transgresses the order of Divine justice, to which he cannot return except he pay some sort of penal compensation, which restores him to the equality of justice (ST I-II, 87,6)
Where 2267 fails is in suggesting that it is the defense of society that determines the proper punishment when in fact, as a secondary objective, this is incorrect; that determination is made by the primary objective which is retribution.
