Vice

A vice is a practice, behaviour, habit or item generally considered morally wrong 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. Vices are usually associated with a fault in a person's character or temperament rather than their morality. Synonyms for vice include fault, sin, depravity, iniquity, wickedness, and corruption. The antonym of vice is virtue.
