What fit punishment?

As Norval Morris observes, however, (Morris, 1974, p. 17) it is virtually impossible for a prisoner to volunteer: no matter how firmly it is said that acting as a medical guinea pig, donating blood, performing some social service, or entering upon an educational or training course will not effect parole chances, the hope will always be present that these activities will favourably be interpreted and will speed release. To place an offender between a long prison sentence and a potentially dangerous and drastic course of medical treatment is to impose a cruel and impossible choice. Does the person who does not opt for castration then 'volunteer' for prison? [...]

[D]o the offenders want to change their orientation and pattern of behaviour? Although, when faced with a prison sentence and other unpleasant consequences, many offenders will readily 'volunteer' for a programme of treatment, it would appear that some paedophiles at least, much in the manner of many homosexuals, do not wish to change their orientation at all, but insist rather that the laws which prohibit their behaviour should be modified.
