The
only purpose of prison should be to reform criminals so they can be let back into society once they are no longer deemed a danger (i.e. that means indeterminant, not fixed, sentences). I regard a criminal more like a bad part which needs to be fixed. You don't hit your car with a hammer to punish it if it breaks (unless you're Cougtek
), nor should we do the same with human beings. And in the same way some cars break down beyond repair, some people are just beyond reform. Their minds are hopelessly broken beyond any hope of "fixing". This is a case where it makes sense to remove the person permanently from society. The best way is to put them somewhere isolated by geography, with no chance of escape, and where society won't need to spend money guarding them or feeding them. Naturally, such a place would be hell on earth for whomever is sent there, so we should offer a choice between permanent exile and death in the interests of being humane. In this particular case, I'd be dubious that the person who did this could be reformed. I might say try for 10 years. If not, give him a choice of exile or death.
The big problem as I see it with many justice systems is the total lack of any attempts at reform. If you get to some criminals early, while they're still in the petty crime stage, you can avoid major expense down the road.
