Which defense asserts lack of mental capacity to understand wrongfulness?

• A. Self-defense
• B. Insanity
• C. Entrapment
• D. Duress

Answer: (B)

In criminal law, the defense that hinges on a defendant’s lack of capacity to understand that their act is wrong is insanity. This defense argues that because of a mental disease or defect, the person could not grasp the nature of their act or appreciate that it was morally or legally wrong at the time it was committed. If that standard is met, the person can be found not guilty by reason of insanity. This differs from self-defense, which rests on a reasonable belief of imminent danger and the appropriate response to it; entrapment, which involves police inducing someone to commit a crime; and duress, which involves being forced to commit a crime by a threat. The insanity standard centers on the defendant’s cognitive understanding of wrongfulness rather than external pressure or immediate danger.
