The Scariest Serial Killers in History

The scariest serial killers, with info about their methods, victims, and more. Serial killers are among the most terrifying people imaginable, partially because of how unfathomable their crimes can be. Most serial killers kill randomly, looking for a specific type of victim in the dead of night, whether they’re tall, blonde women or short, elderly black men. Any type of person can be prey to a certain type of serial killer. Many of these heinous evildoers have been known to rape and torture their victims. Some have even made meals out of their victim’s dead bodies.


One of the things that make serial killers so scary is that anybody can be a victim, and anybody can be the culprit. Many of the worst serial killers were friendly neighbors or easy-going coworkers that one would never suspect of secretly having human heads in the fridge. The serial killers on this list are among the scariest villains in history due to their methods, their motives, and their personalities.

    Although Rodney Alcala killed anywhere between 8 and 130 women, he was best known as The Dating Game Killer, because he was a contestant of the popular game show just before he was caught. Alcala tortured and strangled his victims after taking sexually explicit photos. Alcala had ultimately won a date on The Dating Game, but the date never happened because he was deemed too creepy. The rejection was seen by some as a reason for his killings, but he had already killed at least 4 people by that point. He was caught in 1979 and sentenced to death.
