The child grows up with the feelings of dominance and control because they were never shown compassion because they were abused as a child.
Parents are usually the explanations people come up with when the questioning of a serial killer comes into play. Mothers are the most influential in determining whether a child's experiences as a child made him out to be a serial killer. A great amount of serial killers are found to have unusual or unnatural relationships with their mothers there are three categories of mothers, monstrous mothers, uptight mothers, and loose mothers. The mothers seem to be the key role in serial killers lives because with Ed Gein his mother was very religious and convinced him that women were "vessels of sin and caused disease." With this impression of women sketched in his mind he grew up to act out what his mother had taught him because he made vessels out of women, he used their skulls for bowls and other objects. Then there's Ed Kemper who beheaded him mother, shoved her vocal cords down a garbage disposal, and then raped her headless body, only to say that "I certainly wanted for my mother a nice, quiet easy death like everyone else wants." The worst of all types are those mothers classified as loose mothers; these mothers overstep boundaries, exposing their children to inappropriate sexual behavior. That's the psychological reasoning behind serial killer Bobby Jo Long, who killed women characterized as sluts and whores because he said they reminded him of his own mother. Then there's the typical sadistically disciplinarian father who berates his son and calls him sissy and failure that always the story of abuse being brought to life. For instance, Albert Desalvo's father brought home prostitutes and brutally beat Desalvo's mother while Desalvo watched. He was sold off as a slave and when he did not move fast enough to get a task completed he was busted in the back with a pipe.
