Whether anger should be reckoned among the capital vices?

Objections

Objection 1 : It would seem that anger should not be reckoned among the capital sins. For anger is born of sorrow which is a capital vice known by the name of sloth. Therefore anger should not be reckoned a capital vice.
Objection 2 : Further, hatred is a graver sin than anger. Therefore it should be reckoned a capital vice rather than anger.
Objection 3 : Further, a gloss on Prov. 29:22, "An angry [Douay: 'passionate'] man provoketh quarrels," says: "Anger is the door to all vices: if it be closed, peace is ensured within to all the virtues; if it be opened, the soul is armed for every crime." Now no capital vice is the origin of all sins, but only of certain definite ones. Therefore anger should not be reckoned among the capital vices.
