Kakia is the personification of vice, moral badness and sin in Greek mythology. She is the counterpart of Arete, who represents moral virtue. She is depicted as a vain, plump and heavily made-up woman dressed in revealing clothes, which she uses to tempt people into sin. She appeared before Heracles, alongside Arete, at a crossroads. She attempted to tempt him but he chose Arete over her.
