A more thorough explanation:

A psychopath is a person who has a mental disorder that makes them extremely antisocial. This can lead to aggressive, perverted, or criminal behavior. The formal psychiatric term for this mental illness is called antisocial personality disorder.

For example, a psychopath may have no regard for the feelings or safety of others and may engage in criminal activities without feeling any guilt or remorse. They may also manipulate and deceive others for their own gain.

It is important to note that not all people with antisocial personality disorder are psychopaths, and not all psychopaths have this disorder. However, the terms are often used interchangeably.
