Social Scientific Explanations 1. PSYCHOPATH / SOCIOPATH Don’t feel guilt Problem all serial killers are psychopaths, but not all psychopaths are serial killers 2. MEDIA VIOLENCE AND PORNOGRAPHY Ted Bundy quote Problem millions have seen this but serial killers are rare

3. ELLIOT LEYTON QUOTE “These people are social outcasts whose career or class ambitions haven’t been fulfilled. They blame this on a particular group.” First they have violent fantasies about the group, then in a tiny proportion of cases they act out these fantasies. The reason there are more serial killers today then ever before may be because society is changing so fast and leaving more people behind. Problem Most social outcasts don’t kill - only a partial explanation
