Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors. Nurture is generally taken as the influence of external factors after conception, e.g., the product of exposure, life experiences and learning on an individual.

It is time to bring nature (genetics) together with nurture (environment) in the study of social development. First, initial research findings on three key domains of social development (attachment, empathy, and social competence) suggest that genetic factors contribute to individual differences in social development.

In general, nature looks at the impact of such physical approaches as neurotransmitters and genome sequencing on child development, while nurture focuses on aspects such as peer pressure and social influences.

Nurture refers to all the environmental variables that impact who we are, including our early childhood experiences, how we were raised, our social relationships, and our surrounding culture.

Significant evidence shows that nurturing others improves society’s well-being. The once ubiquitous debates about nature vs. nurture have become much less common. Instead, it has become apparent that both our genetic nature and our environments affect our behavior.

Fantasy is the driving element in the serial killer’s life, and as a result plays an integral role in the murder itself. The killer is not only pushed to kill by their thought patterns (Ressler, 1988) , but is essentially incited to murder by an intrusive fantasy life (Burgess, 1991).

Hybristophilia is a sexual interest in and attraction to those who commit crimes, a paraphilia in which sexual arousal, facilitation, and attainment of orgasm are responsive to and contingent upon being with a partner known to have committed a crime.

Born in El Paso, Texas, Ramirez’s childhood is considered an influence on his crimes. His father, Julián, was prone to fits of anger that often resulted in physical abuse, causing Ramirez to seek escape by sleeping in a local cemetery. Ramirez also began using LSD and cultivated an interest in Satanism.

Richard Ramirez, who died in 2013, checks in for the Devil’s Night. Liz Taylor leads him to his room, where a married couple is sleeping. After killing the husband, the wife runs screaming from the room, where she is killed by James March.

Biological factors such as breeding behavior, care of young, time of last eating, and food storage cause changes in daily activity patterns. Similarly, environmental factors such as temperature, snow cover, food supply and disturbance caused by humans in an urban setting also cause changes in daily activity patterns.

Serial killers differ in many ways, including their motivations for killing and their behavior at the crime scene. However, attendees did identify certain traits common to some serial murderers, including sensation seeking, a lack of remorse or guilt, impulsivity, the need for control, and predatory behavior.

As does infancy, early childhood is key to the formation of a serial killer. Commonly, serial killers were isolated from their peers as children (Vronsky 2004). Many serial killers suffered from weight problems, stutters and learning problems such as dyslexia (Moesch 1998).

Many serial killers are survivors of early childhood trauma of some kind – physical or sexual abuse, family dysfunction, emotionally distant or absent parents. Trauma is the single recurring theme in the biographies of most killers.

Over the course of his work, which began in 1979, Vronsky has deduced that serial killers generally develop the personality and compulsion befitting a killer when they’re young — by the time they’re 14, they’re basically fully formed; they generally start killing in their late twenties.
