They question whether an individual can be held accountable for his actions by the society that raised him, educated him, influenced him, and if the individual seemed aberrant relative to all that, it must be because of his particular neurology which enables him or prevents him from being influenced by the society, or allows him to be influenced by the "darker" aspects of society.
