Whether shamefacedness is about a disgraceful action?

Objections

Objection 1 : It would seem that shamefacedness is not about a disgraceful action. For the Philosopher says (Ethic. iv, 9) that "shamefacedness is fear of disgrace." Now sometimes those who do nothing wrong suffer ignominy, according to Ps. 67:8, "For thy sake I have borne reproach, shame hath covered my face." Therefore shamefacedness is not properly about a disgraceful action.
Objection 2 : Further, nothing apparently is disgraceful but what is sinful. Yet man is ashamed of things that are not sins, for instance when he performs a menial occupation. Therefore it seems that shamefacedness is not properly about a disgraceful action.
Objection 3 : Further, virtuous deeds are not disgraceful but most beautiful according to Ethic. i, 8. Yet sometimes people are ashamed to do virtuous deeds, according to Lk. 9:26, "He that shall be ashamed of Me and My words, of him the Son of man shall be ashamed," etc. Therefore shamefacedness is not about a disgraceful action.
Objection 4 : Further, if shamefacedness were properly about a disgraceful action, it would follow that the more disgraceful the action the more ashamed would one be. Yet sometimes a man is more ashamed of lesser sins, while he glories in those which are most grievous, according to Ps. 51:3, "Why dost thou glory in malice?" Therefore shamefacedness is not properly about a disgraceful action.
