Explain the key points of the theory and how you think it applies to explaining the whys of serial killing.

Social structure theories focus on individuals’ socioeconomic standing, suggesting that poor people commit more crimes because they are stifled in their quest for financial or social success. Social process theories contend that criminal behavior is a function of a socialization process. Offenders may turn to crime as a result of peer-group pressure, family problems, poor school performance, legal entanglements, and other situations that gradually steer them to criminal behavior. Labeling theory views abnormal behavior as a process by which a person graduates from primary deviance to secondary deviance. Serial killers have been linked to childhood maladaptive behaviors, known as the MacDonald Triad, such as torturing animals, enuresis or chronic bed-wetting, and fire-setting.
