Whether the debt of punishment is an effect of sin?

Objections

Objection 1 : It would seem that the debt of punishment is not an effect of sin. For that which is accidentally related to a thing, does not seem to be its proper effect. Now the debt of punishment is accidentally related to sin, for it is beside the intention of the sinner. Therefore the debt of punishment is not an effect of sin.
Objection 2 : Further, evil is not the cause of good. But punishment is good, since it is just, and is from God. Therefore it is not an effect of sin, which is evil.
Objection 3 : Further, Augustine says (Confess. i) that "every inordinate affection is its own punishment." But punishment does not incur a further debt of punishment, because then it would go on indefinitely. Therefore sin does not incur the debt of punishment.
