Whether anger is more grievous than hatred?

Objections

Objection 1 : It would seem that anger is more grievous than hatred. For it is written (Prov. 27:4) that "anger hath no mercy, nor fury when it breaketh forth." But hatred sometimes has mercy. Therefore anger is more grievous than hatred.
Objection 2 : Further, it is worse to suffer evil and to grieve for it, than merely to suffer it. But when a man hates, he is contented if the object of his hatred suffer evil: whereas the angry man is not satisfied unless the object of his anger know it and be aggrieved thereby, as the Philosopher says (Rhet. ii, 4). Therefore, anger is more grievous than hatred.
Objection 3 : Further, a thing seems to be so much the more firm according as more things concur to set it up: thus a habit is all the more settled through being caused by several acts. But anger is caused by the concurrence of several passions, as stated above (Article [1]): whereas hatred is not. Therefore anger is more settled and more grievous than hatred.
