Recent researches on deviant behavior have taken a relativistic approach, where deviant behavior can be defined differently if placed in different contexts or situations. Based on this approach, this paper attempts to debate on the possible influences that deviant behavior might have on students' moral development, and proposes that deviant behavior can provide opportunities for moral education and have positive effects on one's moral development. The paper also attempts to devise effective strategies to promote students' moral development by engaging students to evaluate instances of deviant behavior.
