The word psychopath is often used loosely as a term of abuse. That weakens its value. A more useful approach is to describe the traits involved: lack of empathy, shallow emotion, manipulation, absence of remorse, appetite for risk and willingness to use other people as instruments.
These traits are observable. That gives judgement an empirical basis.
The difficulty is that they do not always produce obvious criminality. A person may be cold, deceitful and ruthless while remaining outwardly successful. Indeed, some institutions may reward those qualities.
Politics is one example.
Leadership requires confidence, decisiveness and the ability to withstand criticism. But these qualities can resemble, or conceal, dominance, vanity and indifference to suffering. A leader who hesitates before sending others into danger may appear weak. One who acts without hesitation may appear strong.
The political system can therefore select for precisely the traits that would alarm us in private life.
This does not mean that all leaders are psychopathic. Nor does it mean that psychopathy alone explains war, oppression or corruption. Institutions, ideology, ambition, fear and group loyalty also matter. Yet people with unusually weak empathy and a strong desire for control may be particularly well suited to climbing organisations built upon competition.
They are often persuasive. They may read other people accurately without sharing their feelings. They learn what language inspires loyalty, fear or resentment. Their intelligence serves strategy rather than sympathy.
The problem becomes more serious when such people acquire power.
An ordinary manipulator can damage a family or workplace. A political leader can command armies, direct bureaucracies and shape public belief. Modern technology extends that reach still further. Artificial intelligence can analyse populations, refine propaganda, automate surveillance and translate a leader’s intention into action on an immense scale.
AI does not supply the desire to dominate. Human beings do.
This is why the question of control matters more than the fantasy of a machine suddenly becoming evil. A system without ambition can become the instrument of an ambitious person. Intelligence without conscience may serve a will without restraint.
Our institutions are meant to prevent this. Laws, independent courts, a free press, elections and divided powers place obstacles in the way of arbitrary rule. But institutions depend upon people respecting limits. A leader who regards every limit as an enemy will attempt to weaken them.
Such a person may justify each step in reasonable language. Secrecy becomes security. Surveillance becomes protection. Censorship becomes responsibility. Aggression becomes defence. Reason becomes the advocate of appetite.
The signs are therefore behavioural rather than metaphysical. Does the leader accept correction? Show concern for suffering outside his own group? Admit error? Respect restraints when they obstruct him? Treat opponents as fellow citizens or as enemies to be destroyed?
These questions are more useful than asking whether someone is simply good or evil.
The greatest political danger may come from a small minority whose capacity for attachment, empathy and remorse is unusually weak, operating within systems that reward confidence, aggression and manipulation.
The answer is not to diagnose every disliked politician. It is to build institutions that assume power may attract people least suited to exercise it.
Good government cannot depend upon the goodness of those who govern.
