If a child is neglected or abused by a parent or guardian, such bad behavior or mental disorders may develop. “According to Sigmund Freud, the development of the unconscious personality in early childhood will influence behavior for the rest of life” (Freeman, web). When a child has no foundation to learn from, he cannot learn how to be ethical. Furthermore, the child may not be able to be empathetic and learn to understand the feelings of others. “Childhood adversities, such as abuse, neglect, parental loss, and other stressful experiences, are estimated to account for 45% of the variance in childhood-onset psychopathology and 26-32% of the risk of early-onset psychiatric disorders late” (Hamburger, web). An example of a child suffering from lack of parenting is a man named Charles Manson. He grew up in a very unstable home. His mother was a sixteen-year-old prostitute who tried to sell him for a bottle of alcohol. As he grew up, he moved between different family members as his mother was unable to raise a child. Manson said in his own words, “Rejection, more than love or acceptance, has been a part of my life since birth” (Emmons, p. 24). As a result of such neglect and abuse, Manson created an occult. He made the occult people his new family that he could control. He then manipulated them to kill more people. Manson has been named the most dangerous man alive and has a book about his life experiences before the murders (Emmons, web). Another serial killer who was abused as a child is John Wayne Gacy. He was molested by his uncle on multiple occasions. He then raped and killed thirty-three young men
