I'll just add that fortunately for all of us, the diagnosis of psychopathy is very rare. We're talking about an extremely small number of people. For those who may be amenable to treatment and reintegration, my understanding is that the Correctional Service of Canada, which is strained for resources, often doesn't offer any program unless it's close to the potential release date, so we're dealing with a long period of time when habits get ingrained and when behaviour gets ingrained.
I'd also point out that given the offences listed here, not all of the people who commit this type of crime will be psychopaths. I think we have to bear that in mind in dealing with even the limited population identified here.
Again I take us back to the harm reduction comment that was made by my friend. Surely there is value in attempting to offer someone an incentive and some ability to come to terms with what they've done and perhaps at some point become a responsible member of society. For those who are not amenable to treatment, it is only a parole board that can release an offender who is subject to a life sentence. There is no statutory release and there is no warrant expiry, so if the individual is not participating in treatment, doesn't show they've come to terms and that their risk has been reduced, they're not going to be released on parole.
