Whether sorrow can be a virtuous good?

Objections

Objection 1 : It would seem that sorrow is not a virtuous good. For that which leads to hell is not a virtuous good. But, as Augustine says (Gen. ad lit. xii, 33), "Jacob seems to have feared lest he should be troubled overmuch by sorrow, and so, instead of entering into the rest of the blessed, be consigned to the hell of sinners." Therefore sorrow is not a virtuous good.
Objection 2 : Further, the virtuous good is praiseworthy and meritorious. But sorrow lessens praise or merit: for the Apostle says (2 Cor. 9:7): "Everyone, as he hath determined in his heart, not with sadness, or of necessity." Therefore sorrow is not a virtuous good.
Objection 3 : Further, as Augustine says (De Civ. Dei xiv, 15), "sorrow is concerned about those things which happen against our will." But not to will those things which are actually taking place, is to have a will opposed to the decree of God, to Whose providence whatever is done is subject. Since, then, conformity of the human to the Divine will is a condition of the rectitude of the will, as stated above (Question [19], Article [9]), it seems that sorrow is incompatible with rectitude of the will, and that consequently it is not virtuous.
