Base Instincts: What Makes Killers Kill

Decent Essays

The brain can be affected by damage and cause behavior to be expressed differently in every person. Events such as a car crash or childhood abuse can affect brain development and function. Damage to certain areas of the brain can have a variety of effects. The hippocampus controls emotions and is associated with memory, and the frontal lobe is a brain cortex that controls motor functions, problem solving, memory, language, judgments, social and sexual behavior and impulse. When the frontal lobe or hippocampus is affected, a person’s emotion can be out of their control. In criminal cases, brain damage can affect the sentencing of a violent criminal, but to what extent should these abnormalities play a role in their conviction? Much research …show more content…

Jonathan H. Pincus, M.D. wrote a book titled Base Instincts: What Makes Killers Kill? In his book he interviews and studies violent criminals and murderers. One of which he studied was Louis Culpepper, a convicted and incarcerated child molester. When Pincus first met Culpepper he looked the same as any middle aged man, other than the jumpsuit and handcuffs he was wearing. He was calm, collected and had a smile on his face. Culpepper was convicted for molesting his 5-year-old stepdaughter. The event started after Culpepper was in an almost fatal motor accident after being hit by a drunk driver, leaving Culpepper with brain damage. A CAT scan was conducted on Culpepper, which “showed that brain hemorrhages, and blood clots in his entire frontal lobe. Culpepper was left with no motor or sensory losses other than that fact that he lost his sense of smell” (Pincus,16). “Culpeper was left alone in the house with his stepdaughter while recovering and that is when he first got the urge to molest her. One day, when Culpepper’s wife came home early from work she witnessed it happening and spoke to her minister for help who advised her to call the police. Culpepper was then charged with criminal sexual conduct, he faced 20 years in prison.” (Pincus, 16,17).

Mental illnesses can be used as a defense when pleading guilty in a case as well. David Zink, who was to be put to death in 2001 for the murder of a 19-year-old girl, pleaded to be mentally ill in hopes of a chance to live. “David Zink kidnapped, raped and mutilated a 19-year-old girl near Stafford, Missouri.” When on trial Zink’s attorneys stated that he suffered from “antisocial, narcissistic and paranoid personality disorders”. Mr. Zink’s attorneys argued that these mental disabilities gave complete reason as to why he committed the murder and as to why he should be let off. Zink took part in a PET scan of his brain to give the jury as evidence. “The PET scans showed distortions in the brain that were most likely due to being ill with meningitis and mumps in his adolescence years. Zink’s PET scan revealed problems in his amygdala, which is said to control emotions.” Damage to the amygdala has been found in many recent brain studies of other psychopaths alongside Zink. It is said that “psychopaths lack emotion, empathy and guilt, and that could be due to the damage to several psychopaths amygdala’s.” Zink’s attorneys asked for life in prison, however, the jury denied the appeal and Zink was given the death penalty.
