There is a pattern of dysfunctional family relationships in serial killers, as exemplified by the childhoods of Richard Ramirez and John Wayne Gacy. The normal caregiving experience has not occurred between parent and child, so the child does not emotionally develop a sense of self and has no rational concept of right and wrong. When the serial killer carries out his murder plan, the superego is unable to thwart the desires of the id because his parents did not establish the morals and values ​​that make up the superego during their neglectful childhood . Furthermore, the serial killer does not experience the guilt that the ego/superego should release if a sense of right and wrong is secured. The abused child who later becomes a serial killer feels he has no control over his hostile environment, so he imagines a different reality that he can control as a form of comfort. This is where thought disorder begins. The child develops his own idea of ​​empathy and right and wrong in this self-centered fantasy, which ultimately turns him into a sociopath (Garrison, 1996, p. 5-6). Evidently a neglectful childhood experienced by a serial killer is at the basis of the internal process of the catathymic crisis. The sociological theory founded by Albert Bandura called Social Learning Theory can explain why a child who observes a violent parent (or anyone who regularly attends) transgress violence will lead the child to imitate this violent behavior in the future. Social learning theory emphasizes observational learning through direct experience and through human modeling. Observational learning takes the form of three different models: the demonstration of a real individual... center of paper... Wayne Gacy and Richard Ramirez. The sadistic behavior of a serial killer occurs as a direct consequence of the physical and emotional abuse received from a parent. Individuals who were victimized in childhood will become victimized in adulthood because victimization has been modeled on them during developmental stages of development. Furthermore, there is no normal bonding experience that should occur between parent and child, and there is a lack of moral and ethical restrictions that were not implemented during the development of the superego. Not only was the parent-child bond guaranteed, but also the bond between the individual and his society. Therefore, the catathymic crisis, social learning theory, social control theory and the structural model of personality confirm that a neglectful childhood environment is the ultimate cause of the development of a serial killer..
