Imagine a married, middle-aged high school teacher who suddenly started seducing young girls. His behaviour was so brazen that that he was quickly arrested and convicted of molestation; he was sent on a treatment programme, but he was expelled from the programme after propositioning several women there.
Having failed rehab, he was to appear in court for sentencing, but the day before his court date, he passed out after complaining of blinding headaches for several hours. After ordering an MRI, the doctors saw the source of the problem: he had an enormous tumour in his frontal cortex. The tumour was removed, and the deviant sexual urges disappeared immediately and permanently.
The man was no longer a hypersexual monster. However, he was still to face the jury.
Should he be perceived as a serious threat to society, or a rare survivor of a life-threatening health problem?
