Vice is a practice, behavior, or
habit generally considered
immoral,
sinful,
criminal,
rude, depraved, or degrading in the associated society. In more minor usage, vice can refer to a fault, a negative character trait, a defect, an infirmity, or a bad or unhealthy habit (such as an
addiction to smoking). Vices are usually associated with a transgression in a person's character or temperament rather than their morality. Synonyms for vice include fault, sin, depravity, iniquity, wickedness, and corruption.
