The pride refers to an excessive self-love, this has been recognized as the root of all of the vices. The avarice manifests most tangibly in efforts to acquire material wealth or gain, notably the physical or intellectual resources of others, so depriving them of the benefits they might otherwise expect from them. The gluttony is a misplaced desire for food for its sensuality, or withholding food from the needy. The lust includes any form of sexual relationship understood to be abusive attachment to carnal pleasure. The sloth refers to pettiness, cowardice, negligence, being remiss in one's duties, mistrustfulness, indolence, and sluggishness and it may be intepreted as sadness or listlessness. The wrath is understood as inappropriate feelings of hatred, revenge or denial and includes punitive desires outside of justice. And the envy involves the resentful or painful desire for another's advantages or possessions, traits, status, abilities, or situation.
