Over the years it has been debated whether people are born as they will forever be or whether the society they grow up in creates all their attributes. This nature versus nurture debate affects many aspects of life, including the treatment of serial killers and psychopaths, the recognition of emotional and mental disorders, the acceptance of homosexuality, and even the regulation of video games. Nature theory states that only a person's genes develop their personality, while nurture theory states that personality develops only due to the impact of (human) society. This debate has been a controversial issue since the beginnings of sociology, the study of society and its impact on the humans who live in it (Stolley), and it will remain controversial due to the inability of humans to know the origins of the life. Some believe that without authoritarian controls, people are inherently evil and savage due to human nature and evolution, while others believe that people are just a product of their environment and society. If the belief that people are inherently wild and evil is correct, then it must also be true that a person's genes are the only element of their personality. An example of this theory is the evidence that supports the idea that serial killers are inherently evil, according to scientific studies. In a study conducted by Dr. Richard Davidson, people with violent tendencies showed different brain activity than people with normal tendencies. The study subjects had been convicted of murder and aggressive or antisocial disorder and exhibited activity significantly different from that considered normal. Areas of the brain controlling “negative and violent emotions… the impulse of emotion…… middle of article… it must be concluded that the most important factor in human personality and actions is society and the environment in which they are located.
