HATRED. — In general, it is the state of aversion, of persistent enmity toward any object. It is to be considered either as a passion of the sensitive appetite or as a motion of the will.
As a passion, it is aversion to evil insofar as it is unbecoming and harmful to the subject (Sum. Theol., 1°-2°, q. 29, a. 3). If well regulated, it can be of excellent assistance to the higher faculties by spurring them to abhor with all their strength every true evil. Hatred, as an act of the will, is a state of aversion toward a person or another object either because they are evil or abominable ("odium abominationis") or because one desires evil for others in order that it may harm them ("odium inimicitiae").
