Identifying life-long patterns of instrumental aggressive behaviour, and distinguishing instrumental aggression from the broad pool of aggressive behaviour, has the potential to improve understanding of underlying mechanisms, increase the accuracy of risk assessments, and contribute to more effective treatment and management strategies.",
