Crime of hereditary ability?

Many argue that crimes are inherited because the society used to have families whose grandparents, parents, and children were very cruel. There have been many studies and debates on this issue but have yet to reach agreement.

Brusca - the infamous mafia boss was arrested (Photo: BBC) In 1996, the infamous mafia boss Brusca, 39, was arrested. Brusca is an unassuming killer, but his typical brutal act is torture, strangling his 11-year-old son to death and then immersing himself in the acid basin .

Brusca set a bomb to kill judge Judani Falcone, his wife and three bodyguards near Palermo in 1992. He also ordered the bombing in Florence, Milan and Rome, causing the deaths of many others. To capture Brusca, Italian police had to mobilize up to 200 special employees, all covered with black hats to prevent retaliation.

Brusca's grandfather and grandfather were both farmers but people with a relationship with the mafia. His father was Bernado, a true "mafia" godfather , who was sentenced to life imprisonment for a series of murders. His brother, Vinacenzo, was also the wanted object of the police (also arrested with Brusca).

In Vietnam, there was general robber Tran Ngoc Lam, who organized and carried out dozens of frauds and robberies, killing people in Hanoi, Hai Phong, Ho Chi Minh City, Thai Binh . Brother Lam was a security guard at an agency, used AK guns to shoot two people.

And criminal Nguyen Nhu Ngoc has parents who are prisoners. Shortly after giving birth a few days, Ngoc had to leave her mother and was adopted by an advisor. Although being fed with good milk, living in a good environment, she was loved by her adoptive mother, but at the age of 10, Ngoc still dropped out of school, then left home wandering. At the age of 17-18, Jade became dangerous thugs. In the detention place at the age of 18, Ngoc became a fierce bear head, brutally beating other prisoners.

Genetic question

Realizing that families that have been through generations have committed the same crimes as robbery, murder, prostitution, etc., many argue that criminal acts can be genetic. From the end of the 19th century, Dr. Lambrojo (Italian) - a famous anthropologist and criminal, had argued that some people had a kind of innate behavior in it whose nature was guilty. He affirmed that ordinary people cannot become criminals, but evil enemies are born by parents.

In the 60s of the twentieth century there were a few studies of twins with eggs but were raised in two different places. The results show that: When a person commits a crime, the other person is more likely to commit an offense.

Another study of the number of children admitted to adoption also results in children having felony parents more likely to become criminals than children with honest parents.

Robert Cloninjer, a psychologist at the University of Washington (USA), studied 1,500 children and found: In children who live in relatively good environments, their parents have a criminal record, the crime rate is 12. % In children whose parents have a criminal record, living in an unhealthy environment, the crime rate soars to 40%. In children who live in an unhealthy environment but honest parents, the proportion of criminal acts is only 7%.

Many Western criminals support the theory of evil genetics. But genes that guarantee genetics are not proven. Usually, one or more genes play a role in controlling specific enzymes; Maybe these specific enzymes motivate people to commit crimes.

Some scientists suspect that criminal behavior is related to serotonin - a neurotransmitter. Experiments at the University of North Carolina show: Aggressive or disruptive monkeys often have lower serotonin levels than gentle monkeys. Other studies in the United States have also shown that people who commit acts of agitation also have low serotonin levels. And researchers hope to find a drug that increases serotonin, helping people avoid brutal aggression.

Gene encodes Maoa

Dr. Hans Brunner, Nimègue University, Netherlands, has studied the violent behavior of criminals with the same bloodline. Through surveying a family of many men who committed rape, drunkenness, and madness . and based on the family tree of this family, Brunner discovered an interesting thing: No one woman in the above family, they are entangled in the characteristics that lead to the disaster. Since then, he raises doubt, the cause of crime is X chromosome in the pair of sex chromosomes. Most likely the problem lies in the X chromosome of a man.

Later, Brunner also specifically identified a catastrophic gene, the gene that codes for an enzyme called MAOA (Mono Amine Oxydase A). His work was done by Dr. Xanda Breakefield at Boston University Institute (USA), who had previously isolated MAOA 6 years earlier, further clarifying. She said: 'A broken MAOA will not be able to control himself in any case that is provoked, while other ordinary people can overcome it'.

If you say all the criminals have genetic roots that are unbiased. But it is difficult to explain why some families have many people who are aggressive and repeat offenses.

Although scientists have recently studied the completion of a ' human gene map ', of those 60,000-100,000 genes, which genes are encoded to become criminals, it is unknown. sure. Therefore, understanding genetic genes for crimes has been around for a long time, but much more research is needed to produce good evidence.
