This paper attempts to examine the impact of human governance on the complex relationship between Dark Triad traits (narcissism, Machiavellianism, and psychopathy) and deviant workplace behaviours. It integrates the theoretical concepts of Trait Theory, Al-Ghazali's theory of the soul, and Guman’s Governance Philosophy to analyse personality traits, spiritual influences, and ethical principles in deviant behaviours. This study aims to give scholarly insights into the comprehension and application of these significant issues by looking at theoretical and empirical aspects. It focuses on values, ethics, and internal guidance in fostering ethical behaviours and deterring deviant conduct. The study provides valuable insights into the interplay between human governance, Dark Triad traits, and deviant workplace behavior. However, it acknowledges limitations in generalizing findings across different organizational contexts. Further empirical research is needed to validate the effectiveness of human governance principles in mitigating deviant behaviours. The findings offer practical implications for organizational management in promoting human governance principles to cultivate a culture of integrity, transparency, and accountability, reducing the likelihood of Dark Triad traits and deterring the deviant behaviours among employees. The study contributes to existing literature by exploring the role of human governance in addressing these issues.
