Recently, a lot of "instructions" have appeared, telling how you can calculate a potential maniac, for example, by the manner of speech or behavior.
Meanwhile, there is real generalized scientific evidence that shows exactly what characteristics put a person at risk. Let's consult with reputable scientists.
According to experts, heterosexual men between the ages of 20 and 30 most often become maniacs. At work, they are usually "small fry". Often in childhood, such a person was subjected to violence - physical or sexual, or moral humiliation. Many maniacs grew up in single-parent families, did not receive enough warmth, they had difficult relationships with their mothers.
They may have a history of suicide attempts at an early age. All maniacs begin, as a rule, by torturing and killing animals.
Experts distinguish between two types of serial killers. The first is a disorganized killer. His IQ is below average - from 80 to 99. He is closed and isolated from society due to atypical behavior, not socially adapted, suffers from an inferiority complex.
Organized killers have above average IQs of 105 to 120. They are quite socially adapted. Some isolate themselves from society by their own choice, others have a family and other social ties.
Both those and others tend to change their appearance, going to the next crime (for example, changing clothes). Almost all maniacs choose victims according to some specific criteria (appearance, gender, age). As a rule, the crime is preceded by "fantasies" in which the maniac exaggerates his obsession, anticipates the "benefit" from the future murder.
For some maniacs, it is only important that the victim dies. For others, interaction with the victim plays an important role: they can torment her for a long time, torture, etc., they can perform various rituals, including with an already dead body. Sexual satisfaction is not always in the first place. There are many known cases when "serials" had sexual problems, which became the root cause of their antisocial behavior.

All serial killers deal with the victim's body differently. Some just leave him at the crime scene. Others put on display, sometimes performing ritual actions over the corpse (dressing up, making up). Still others hide the body.
Do not think that maniacs are completely crazy: organized killers can perfectly control themselves, carefully tracking down the victim, choosing the best time and place for the crime, calculating everything in detail. Unorganized people usually take advantage of the opportunity, circumstances, act under the influence of a spontaneous impulse.
By the way, recently the German neuroscientist Gerhard Roth discovered the so-called zone of evil in the brain of serial killers, rapists and robbers. This area is located in the central lobe of the cerebral hemispheres and is seen as a dark spot on X-ray images. It was present in most of the criminals Roth examined as part of a science project.
Also, when criminals were shown scenes of cruelty and violence, the brain activity in the zones "responsible" for feelings such as sadness and compassion did not change.
According to the scientist, the cause of criminal behavior can be a malfunction in the brain, such as a tumor or injury in the frontal lobe. There are cases when, after the removal of a malignant formation in the brain, a person's craving for crime disappeared and he returned to normal life, the researcher says. In addition, a deficiency of the hormone serotonin can push for criminal acts.
Professor Roth divides all criminals into three groups. To the first, he refers to mentally healthy people who grew up in a dysfunctional environment where crime is considered the norm. The second includes individuals with mental disabilities who perceive the world as a threat to themselves.
“One wrong look, one wrong move - and such a person can explode and become a murderer,” the researcher states. Finally, he classified the "pure psychopaths" in the third category. In his opinion, it included such famous dictators as Joseph Stalin and Adolf Hitler, who ruled entire nations.
