In Kanaku Choaku, someone considered to belong originally to the evil side (e.g. bandit, hired killer, black-market lender, or woman trafficking broker) is put into a position in conflict with evil for many different reasons (e.g. the emergence of a feeling of justice or a chivalrous spirit against a greater evil, a peer's betrayal, a disagreement about the sharing of the spoils, a power struggle, or greed) and consequently punishes the greater evil (from the other's point of view).
勧悪懲悪（かんあくちょうあく）とは、勧善懲悪において、本来であれば悪に値する存在（強盗、殺し屋、闇金、女衒など）が様々な理由（猛悪に対する正義心や義侠心の発露、仲間の裏切りや取り分の相違、権力闘争、あるいは助平心など）によって、悪と対峙する立場になり、結果的に（他方の視点からして）悪を懲らしめる。
