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>
