Psychopaths are people who have unusual character traits and behavior. They can be overly selfish, manipulative, deceitful and aggressive. Their behavior often results in violation of the rights of others, as well as harm to themselves or others. Psychopathy is a mental illness that can manifest itself in varying degrees and lead to varying health consequences. However, psychopathy can be difficult to diagnose and treat because it can be subtle and asymptomatic. The psychopathic constitution is an attempt to summarize the main behavioral traits of psychopaths and predict their actions. If we take into account that there are quite a lot of people who fall into the described category, then there is something to think about.
