Serial killers are the byproduct of many different things, such as trauma, the death of loved ones, abuse, neglect, adoption and even witnessing abuse (Are Serial). They had to endure a massive amount of trauma and abuse to an unimaginable degree to become who they are. The extent of the abuse, trauma and psychological damage they experience is incomprehensible to many. The destruction of innocence can occur at any time in life, but they are most impressionable in their youth by the negativity of someone else's actions (Scott, Shirley L. "What Makes Serial Killers Tick ~ Childhood Event "). People are sensitive to what they endure during their teenage years, and a cruel upbringing, like that of a serial killer, may determine their future. Many people face tragedy, trauma, abuse, and psychological damage during their lives, but those who experience these issues often progress to serial killers later in life. Statistics show that forty percent of people who resist childhood abuse become excessively abusive, violent, and sadistic criminals because they are burdened with problems for the rest of their lives ("Nurture"). Typically, serial killers are violent and want to torture their victims. Those who were abused as children rarely had any control over anything; as a result, in the future, they want to dominate and inflict on their victim the same pain they faced in their youth. The domination that serial killers crave is usually presented through sexual abuse (“Nurturing”). In childhood, if one has abusive, manipulative or irresponsible parents who neglect them at home, a part of their brain, which controls emotions, is damaged and they become more prone to violence and aggression (White, Sadie. "Making a Monster: The Biological, Social, and Artistic Construction of a Serial Killer From Psychosis to Sondheim").
