Hybristophilia

Hybristophilia is a paraphilia involving sexual arousal by people who have committed crimes; in particular cruel, or outrageous crimes.

The sexologist John Money defines hybristophilia as:

"a paraphilia of the marauding/predatory type in which sexuerotic arousal and facilitation and attainment of orgasm are responsive to and contingent on being with a partner known to have committed an outrage or crime, such as rape, murder, or armed robbery"

This covers Charles Manson's groupies, as well as any other convict who has committed a serious violent crime(s) and is serving life plus for it(them).
