Editing Serial killer (section)

===Hedonistic===
This type of serial killer seeks thrills and derives pleasure and satisfaction from killing, seeing people as expendable means to this goal. [[Forensic psychology|Forensic psychologists]] have identified three subtypes of the hedonistic killer: "lust", "thrill", and "comfort".{{sfn|Bartol|Bartol|2004|p=146}}

====Lust====
Sex is the primary motive of lust killers, whether or not the victims are dead, and fantasy plays a large role in their killings.<ref name="BartolBartol2008"/> Their sexual gratification depends on the amount of torture and [[mutilation]] they perform on their victims. The sexual serial murderer has a psychological need to have absolute control, dominance, and power over their victims, and the infliction of torture, pain, and ultimately death is used in an attempt to fulfill their need.{{sfn|Myers|McElroy|Burton|Recoppa|1993|pp=435–451}} They usually use weapons that require close contact with the victims, such as knives or hands. As lust killers continue with their murders, the time between killings decreases or the required level of stimulation increases, sometimes both.<ref>{{harvnb|Bartol|Bartol|2004|p=146}}, {{harvnb|Holmes|Holmes|2001|p=163}}, {{harvnb|Dobbert|2004|pp=10–11}}</ref>

[[Kenneth Bianchi]], one of the "[[Hillside Strangler]]s", murdered women and girls of different ages, races, and appearance because his sexual urges required different types of stimulation and increasing intensity.{{sfn|Dobbert|2004|p=10-11}} [[Jeffrey Dahmer]] searched for his perfect fantasy lover—beautiful, submissive and eternal. As his desire increased, he experimented with drugs, alcohol, and exotic sex. His increasing need for stimulation was demonstrated by the dismemberment of victims, whose heads and genitals he preserved, and by his attempts to create a "living zombie" under his control (by pouring acid into a hole drilled into the victim's skull).<ref>{{harvnb|Giannangelo|2012}}, {{harvnb|Fulero|Wrightsman|2008}}, {{harvnb|Dvorchak|Holewa|1991}}</ref>

Dahmer once said, "Lust played a big part of it. Control and lust. Once it happened the first time, it just seemed like it had control of my life from there on in. The killing was just a means to an end. That was the least satisfactory part. I didn't enjoy doing that. That's why I tried to create living zombies with acid and the drill." He further elaborated on this, also saying, "I wanted to see if it was possible to make—again, it sounds really gross—uh, zombies, people that would not have a will of their own, but would follow my instructions without resistance. So after that, I started using the drilling technique."{{sfn|MacCormick|2003|p=431}} He experimented with [[Human cannibalism|cannibalism]] to "ensure his victims would always be a part of him".{{sfn|Dobbert|2004|p=11}}

The primary motive of a thrill killer is to induce pain or terror in their victims, which provides stimulation and excitement for the killer.<ref name="BartolBartol2008">{{cite book|author1=Curt R.

Thrill killers murder only for the kill; usually, the attack is not prolonged, and there is no sexual aspect. Usually, the victims are strangers, although the killer may have followed them for a period of time. Thrill killers can abstain from killing for long periods of time and become more successful at killing as they refine their [[Modus operandi|murder methods]]. Many attempt to commit the [[perfect crime]] and believe they will not be caught.<ref>{{harvnb|Bartol|Bartol|2004|p=146}}, {{harvnb|Howard|Smith|2004|p=4}}</ref>

They often use poison, most notably [[arsenic]], to kill their victims. Female serial killers are often comfort killers, although not all comfort killers are female.<ref>{{harvnb|Bartol|Bartol|2004|p=146}}, {{harvnb|Schlesinger|2000|p=276}}, {{harvnb|Holmes|Holmes|2000|p=41}}</ref>
