Various factors such as social conditions, revenge, greed, and psychological problems can encourage a person to commit a criminal act, including premeditated murder regulated in Article 340 of the Indonesian Criminal Code. This qualitative research with a normative fiqh approach examines the causative factors, their relation to the theory of moral development, and the handling of the perpetrators. The results show that the motivation for premeditated murder is still at the preconventional stage of moral development, including punishment orientation and self-interest. Comprehensive handling efforts include early prevention, legal assistance, strengthening the justice system, inter-agency cooperation, rehabilitation, supervision of ex-convicts, victim protection, psychological counseling, international cooperation, law enforcement, and increasing public awareness, with the aim of preventing, handling, and rehabilitating perpetrators and protecting the public.
