Whether envy is a capital vice?

Objections

Objection 1 : It would seem that envy is not a capital vice. For the capital vices are distinct from their daughters. Now envy is the daughter of vainglory; for the Philosopher says (Rhet. ii, 10) that "those who love honor and glory are more envious." Therefore envy is not a capital vice.
Objection 2 : Further, the capital vices seem to be less grave than the other vices which arise from them. For Gregory says (Moral. xxxi, 45): "The leading vices seem to worm their way into the deceived mind under some kind of pretext, but those which follow them provoke the soul to all kinds of outrage, and confuse the mind with their wild outcry." Now envy is seemingly a most grave sin, for Gregory says (Moral. v, 46): "Though in every evil thing that is done, the venom of our old enemy is infused into the heart of man, yet in this wickedness the serpent stirs his whole bowels and discharges the bane of spite fitted to enter deep into the mind." Therefore envy is not a capital sin.
Objection 3 : Further, it seems that its daughters are unfittingly assigned by Gregory (Moral. xxxi, 45), who says that from envy arise "hatred, tale-bearing, detraction, joy at our neighbor's misfortunes, and grief for his prosperity." For joy at our neighbor's misfortunes and grief for his prosperity seem to be the same as envy, as appears from what has been said above (Article [3]). Therefore these should not be assigned as daughters of envy.
