Homolka's former husband, Paul Bernardo, remains in the Kingston Penitentiary. It is very unlikely that he will ever be released, given the severity and number of his crimes. It's fitting that he'll be confined for the rest of his natural life in a narrow and constricted prison cell, since his entire life before his arrest appears to have been founded on the desire to fulfill his every need (sex, power, respect, money). In the immediate aftermath of his arrest and trial, I remember press coverage which highlighted the fact that he owned a copy of the controversial Bret Easton Ellis novel American Psycho. Homolka seems to have been interested in this theme as well: Stephen Williams' Invisible Darkness mentions her fascination with gory crime and horror books, and one 2000 article in The Guardian reports that the copy of American Psycho actually belonged to Karla. I don't think that it would be too much to assume that American Psycho's graphic recounting of the multiple crimes of Patrick Bateman managed to influence them both.
American Psycho was widely criticized at the time for providing Paul--or the Homolkas as a unit--with a blueprint for mass murder. Both Frank Davey's Karla's Web (better, I think, than the eye review has it) and Stephen Williams' tome stress the extent to which they wished to become successful in every possible domain, to become prosperous suburbanites while retaining their secrets to themselves. At first reading, American Psycho does seem to describe this sort of situation, showing the co-existence of Bateman's immense material success and his high social standing with his multiple gratuitous crimes. I first read American Psycho expecting some superficial, gratuitous, and highly unartistic waste of paper. Instead, I found a fairly acute satire of Reagan's 1980s, of a person so deadened by his consumerist desires that not even the most barbaric savageries made him feel like a human being. Nothing that he did ever provoked Bateman into real feeling.
These idiots missed the point of American Psycho entirely.
