Whether contrition should be on account of original sin?

Objections

Objection 1 : It would seem that contrition should be on account of original sin. For we ought to be contrite on account of actual sin; not by reason of the act, considered as a kind of being, but by reason of its deformity, since the act, regarded in its substance, is a good, and is from God. Now original sin has a deformity, even as actual sin has. Therefore we should be contrite on its account also.
Objection 2 : Further, by original sin man has been turned away from God, since in punishment thereof he was to be deprived of seeing God. But every man should be displeased at having been turned away from God. Therefore man should be displeased at original sin; and so he ought to have contrition for it.
