Over the years, the serial killer movie fan base has solidified even more, encouraging filmmakers to bring more and more macabre and heinous crime narratives to our screens. Even fans have welcomed such movies with open hands and have developed a sense of fascination with these twisted characters, who lack empathy and have no control over their actions, resulting in several brutal crimes. While some serial killers roots come from their past traumatic experiences or some kind of abuse, others might simply be the result of being exposed to a violent environment or genetic abnormalities, but not all these factors are always the case or to be blamed because some serial killers are hard to comprehend — they are just psychopaths.
