Why do serial murderers kill?

They kill for fun. They enjoy the thrill, the sexual gratification, and the dominance they achieve over the lives of the victims. The serial killer rarely uses a gun because this method is too quick and would deprive him of his greatest pleasure, exaltiny his victim’s suffering. Serial killers are not insane; they are “more cruel than crazy,” Fox and Levin have their own typology of serial killers, which they describe as follows:

• Thrill killers strive for either sexual sadism or dominance. This is the most common form of serial murderer.

• Mission killers want to reform the world or have a vision that drives them to kill.

• Expedience killers are out for profit or want to protect themselves from a perceived threat.
