Psychopathy is a mental health condition where people have trouble feeling emotions like love and guilt, or understanding how their actions can affect other people. They often come across as selfish and unempathetic, and may do things that hurt or scare people without feeling bad about it. This can include lying, cheating, stealing, or even violence. People with psychopathy don't really have an understanding of right and wrong and may not be able to change their behavior even if they want to.
