A criminal psychological profile attempts to supply investigators with unambiguous information concerning an offender based on the assessment of some significant variables. Profiles do not identify the particular individual who perpetrated the felony, but rather depict the type of individual who is most expected to have perpetrated the offence. Creating a criminal psychological profile involves an in-depth study of the victim and the crime scene as well as sociological and psychological data. Variables Multiple Personality Disorder
Serial killers have a multiple personality structure and an overwhelming urge to kill, which becomes intolerable that eventually takes over them. Serial killers, in the midst of their criminal acts, consider that their personalities had been taken over, whereby they befall like witnesses to their own acts. Sociopathic Features Individuals with sociopathic features obtain satisfaction from killing. These motivational dynamics are regarded by patterns that are consistent with the serial killer, who kills several victims over a period of time for no perceptible reason other than the release of tension and that of pleasure.
Fantasy Serial murderers use fantasy from their childhood to escape from unconstructive family environment. In their own fantasies, they approach a world where they are in control of everything. They obtain contentment from retribution by turning the tables and employing power over another. As they grow up, the misdemeanour itself develops into a fantasy acted out by the serial killer (Lindner, n. d. ). Mood Disorder Serial murderers have an unusual and unrecognized type of mood disorder, that they feel highly addicted from the result of their experience in perpetrating murders.
Serial killers are sociopaths, and study has revealed that sociopaths have high levels of dopamine activity or of feelings of bliss (Lindner, n. d. ). The Hydraulic Affect Serial murderers have a sociopathic personality and character structure. This predisposes them towards having a mechanism that induces ego displacement. Consequently, serial murderers believe that they are motivated in committing crimes because of emotional disorders under unique conditions of extreme mental pressure. Conclusion
Serial killers are mutually a result of nurture and nature. Serial killers are manipulated to some degree by their minds’ unconscious contents, which are reproduced in their behaviour. Therefore, psychological profiling is significant in assisting investigations on serial killings because crimes of these types have a tendency to disclose something in relation to the offender’s behaviour and personality.
