Violent behavior and psychopathic predispositions were long considered, and through many studies, to be adaptive traits that should provide a reproductive advantage. Of course, more current research refutes this view. Studies of tribal peoples found no real advantage for killers in the number of children over non-killers. Studies of psychopathic personalities, while showing their success in romantic relationships (which is explainable by manipulative behavior and the ability to use the feelings of others for their own benefit), do not always show success in long-term relationships and having children. These conclusions, which at first glance seem counterintuitive to many, are actually very logical if we look at what violent individuals are like and how this affects success in continuing the lineage.
It is worth asking one simple question: why would a violent individual need children at all? The answer to this question is quite obvious in the case of normal people, who would like to care for someone, raise someone, leave something behind for the future, simply because they feel a need for it. But violent people are far less concerned with such things; they are more interested in direct personal gain here and now, which the need to care for someone or worry about the distant future can only hinder. Of course, this does not mean that such feelings are entirely absent in violent individuals; they can be expressed as much as in normal people. But at least on average, one should expect this from them less often.
Even if you simply browse the internet, for example, visit the site “Quora,” where various people communicate in a question-and-answer format, you can see confirmation of what current research says. As an example, let’s take a comment from a woman answering a question about whether psychopaths want to have children. She points to both her own selfishness, unwillingness to care for someone and spend her time, as well as the negative aspects associated with having children. She believes that most parents are unhappy, and that having children is a “hellish cult.”
However, it should be noted that there are reasons why a psychopath may strive to have children. First, let’s note social influence. In the past, consciously and openly refusing to start a family and continue the lineage was something unacceptable and condemned; such a person would likely be considered abnormal by many. Such pressure could have played its part, just as its absence certainly plays a part in the modern world, where the refusal of family and children is becoming an absolutely normal personal choice. Of course, a normal person with the previously mentioned feelings will often still be inclined to have children, at least one child. But for a psychopath in such conditions, there is a much higher probability of becoming a staunch “childfree” (no offense to non-violent people who have decided not to have children).
Reasons could also include a person’s personal beliefs, the social influence that still remains in some situations encouraging the having of children and condemning the refusal of it, or even simply an accidental pregnancy. But even if a psychopath does have a child, they are unlikely to influence them in a positive way. On the contrary, the result will most likely be psychological trauma for the child, which will only reduce their own reproductive success in the future. As we can see, violence is once again not an adaptive trait in the long term.
It is good that psychopaths are nevertheless less successful in continuing their lineage than normal and mentally healthy individuals, especially in modern social conditions. Although it would be even better if none of them had or raised children, at least until an effective therapy for their condition is developed, aimed at restoring the function of the missing mechanism of violence inhibition.
