Neuroskeptic, earlier this week, wrote this very powerful (and sad) post about the story of an anonymous man, who after several surgeries removing parts of his brain, developed sexual urges directed toward minors. He developed a case of the rare Klüver-Bucy Syndrome. KBS is a behavioral disorder that occurs when the right or left temporal medial lobes of the brain are damaged. One of the symptoms of KBS is altered sexuality, which can be defined as: characterized by a heightened sex drive or a tendency to seek sexual stimulation from unusual or inappropriate objects.

In this anonymous subject’s case, the inappropriate objects were prepubescents. He was arrested in 2006 and charged with knowingly and wilfully possessing material which contained at least three images of child pornography. The intent requirement of this crime was the key factor in the fight over his sentence. On his behalf, the argument was made that because of the damage to his brain and the resultant KBS, he was not in control of his hypersexual urges. The prosecution countered that since he was able to prevent himself from acting out in public (I wonder if that’s really the case or if that’s a bit of reverse logic), he was able to control his urges, and thus any criminal act was wilfull and knowing.

In his particular case, the judge accepted the mitigation provided by the defense and sentenced the man to the minimum permissible. [Note that after being put on anti-depressants and other medicine, his urges went away.] But, as Neuroskeptic notes, there is a very interesting question here. If the science does prove at some point down the road that pedophiles really are not in complete control of their urges and these urges are the result of a brain malfunction – an organic disorder, if you will – must we change our attitudes toward those that commit these crimes?

Neuroskeptic notes a striking similarity between the behavior of monkeys with similar brain damage and humans:
