Bundy is surprisingly forthcoming in his attempts to explain and understand how he came to be a monster. There are a number of responses that seem decidedly un-psychopathic. He has no problem taking full responsibility for the murders and he realizes that he is very different from other people.
Bundy claims that he was from a good home and was never abused, and that it was his exposure from soft to violent pornography that made his fantasies become more and more violent; one could raise the argument that it was simply stumbling across violent pornography as a child that constituted the abuse necessary to traumatize and stymie the development of his brain.
He speaks of the need to murder (which included necrophilia) as an addiction. Keppel, one of the detectives who helped to apprehend Bundy explained that Bundy experienced the desire for necrophilia as a chemical tidal wave, like an addiction to a narcotic. It certainly seems like his frontal lobe, and the connections between it and the limbic system, failed to control and inhibit his desires.
The interview does not strike me as a manipulation or an attempt to spread lies, but of course that can’t be ruled out. He does, however, appear to respect his interviewer.
This is a good interview with Bundy, which anyone interested in the development of extreme human behaviors should watch.
