In which disorder does a person exhibit aggression against the environment through violence and deceitfulness?

Conduct disorder is characterized by a pattern of behavior in which an individual exhibits aggressive actions towards people and animals, along with behaviors that are often deceitful or violating societal norms. This can include actions such as bullying, initiating physical fights, using weapons, stealing, and other forms of serious rule-breaking. The key feature of conduct disorder is the persistent pattern of behavior that reflects a disregard for the basic rights of others, and it often leads to significant impairment in social, academic, or occupational functioning.

In contrast, adjustment disorder typically involves emotional or behavioral symptoms in response to a stressor, but it does not inherently include aggression or deceitfulness as defining characteristics. Anxiety disorders are characterized by excessive fear or worry but do not align with aggressive or deceitful behaviors. Personality disorders may involve various maladaptive patterns of behavior and cognition, but not all types involve aggression or deceitfulness emergently like in conduct disorder. Therefore, conduct disorder stands out as the most fitting description for the exhibited behaviors of aggression towards the environment through violence and deceitfulness.
