What Is the Difference Between vicious, villainous, and nefarious?

Vicious and villainous are two wicked synonyms of nefarious, and, like nefarious, both mean "highly reprehensible or offensive in character, nature, or conduct." But these synonyms are not used in exactly the same way in all situations. Vicious may imply moral depravity or it may connote malignancy, cruelty, or destructive violence. Villainous applies to any evil, depraved, or vile conduct or characteristic, while nefarious (which derives from the Latin noun nefas, meaning "crime") suggests flagrant breaching of time-honored laws and traditions of conduct.
