@drkevthedarkprofessor: Have you ever wondered where sadism comes from? Why would evolution produce humans who enjoy hurting others? ๐ In this video I talk about the evolution of Sadism, looking at how thousands of years of human behaviour has resulted in everyday sadistic behaviour that we see today. Any thoughts on evolutional/modern everyday sadism? Let me know in the comments ๐ #psychopath #psychology #darkpsychology #truecrime #darktriad
