Aristotle considered shame a "quasi-virtue" in that if you feel shame it’s because you’ve done something non-virtuous, but if you’re unable to feel shame — shameless — you are in need of a virtue that you lack.

The fear of shame can be a useful goad to virtuous behavior, see Dante, Inferno: “But shame soon interposed her threat, who makes / the servant bold in presence of his lord.”
