Every vice is only an exaggeration of a necessary and virtuous function.

Vice often rides triumphant in virtues chariot.

Many a man's vices have at first been nothing worse than good qualities run wild.

This is the danger, when vice becomes a precedent.

He who hates vices hates men.

Men are more easily governed through their vices than through their virtues.

Jupiter has loaded us with a couple of wallets: the one, filled with our own vices, he has placed at our backs; the other, heavy with those of others, he has hung before.

For lawless joys a bitter ending waits.

Vice is a monster of so frightful mien, As to be hated needs but to be seen; Yet seen too oft, familiar with her face, We first endure, then pity, then embrace.

Every vice has its excuse ready.
