Criminality and moral dysfunctions: neurological, biochemical, and genetic dimensions

In this article, the author attempts to demonstrate a relationship between neurobiological dysfunctions and/or genetically determined deviant behavior and personality traits as well as moral abnormalities. Data from neuroscience show that a number of neurological dysfunctions are linked to cognitive and emotional disturbances. Cognitive and emotional abnormalities, in turn, are frequently related to moral dysfunctions. Moreover, neurological disorders can produce dramatic psychological and social problems, personality changes, and behavioral problems in patients. Those mental, emotional, and psychosocial problems and related moral dysfunctions are frequently linked to violence and/or criminal behavior. Genetic research found evidence of inheritability of antisocial traits, which interfere with moral development and activities. This information has consequences for any assessment and disposition within the legal system. More research on the interrelationship between neuro(bio)logical, genetic, emotional, and mental aspects of moral dysfunctions is needed for the development of adequate treatment, prevention, and intervention programs.
