Pride is the highest. What are examples of pride? Attitude or action? Can it be successfully eliminated?
I always believed Sloth was the highest, but now I learned something when I looked more into it thanks to this thread:
Pride is an inordinate desire of our own elevation and a vain complacency in ourselves. All vices spring from pride. The chief of these are vainglory, boasting, luxury, pompousness, haughtyness, ambition, hypocrisy, presumtion, obstinancy, disobedience, self-delusion with regard to our own defects.
Sloth produces idleness, loss of time, negligence, ignorance, inconstancy in keeping good resolutions, tepidity, temptations of all kind and cowardice which disposes us to yield to them.
Covetousness (Greed) is an inordinate love of money and the goods of this world. It produces neglect of salvation, selfishness, hardness towards the poor, craftiness, injustice, quarrels; to say nothing of cares, anxieties and murmurings against Divine Providence.
Lust, or the vice opposed to chastity, and forbidden by the sixth and ninth commandments is the vile source of innumerable sins. Moreover, the criminal affection for carnal pleasures produces disgust for piety, darkness of the understanding, hardness of heart, the diminution and even extinction of faith. It destroys the health of the body and the noblest qualities of the soul, brings trouble and ruin upon families, and often leads to final impenitence.
Anger is an emotion or an inordinate transport of the soul, which causes us violently to reject what displeases us, and impels us to take revenge on those who contradict us. The effects of anger are hatred, revenge, obscene language, cursing, blasphemies, outrages, sometimes dueling and murder. Anger becomes a mortal sin when the emotion goes so far as to extinguish the love of God and our neighbor and makes us blaspheme and commit other sins of serious gravity.
Gluttony is an inordinate love of eating and drinking, or the evil inclination that inclines man to the immoderate use of food and drink. The slaves of this degrading vice stoop so low as to make a god of their belly (Phil. iii.). Gluttony produces drunkenness, impurity, outbursts of passion, blasphemies, angry quarrels, blows or threats, heaviness of soul, disgust for spiritual things, disregard of the laws of the Church for fast and abstinence.
Envy is the sadness that springs from witnessing the spiritual or temporal good of another, because it seems to lessen our own, or our own merit. This vice engenders rash judgments, detraction, malicious joy at the faults or disgrace of our neighbor, hatred and vexations of all kinds.
