Although scholarly interest in morality and situational factors in juvenile offending has grown, few studies have examined their interactive effects on serious offenses. This study addresses that gap by investigating how a risky lifestyle moderates the relationship between moral deficiency and serious juvenile offending. The findings show that both moral deficiency and risky lifestyle independently increase the likelihood of serious offending. Adolescents with weaker moral constraints and greater exposure to criminogenic environments, such as unstructured socializing and delinquent peers, are more vulnerable. Interaction and marginal effects analyses reveal that the influence of moral deficiency intensifies with increased engagement in risky lifestyles. These results support an amplification effect and offer important implications for prevention strategies aimed at reducing serious juvenile offending.
