No, not really. It didn't prevent the murder. It just is an absolute way of knowing they will never murder again. The thing is that many don't ever re-murder.

No, not really. It didn't prevent the murder. It just is an absolute way of knowing they will never murder again. The thing is that many don't ever re-murder. With the proper systems in place, the majority of folks don't even wind up back in prison. IE, Norway's recidivism rate is around 20-25% :: The US hosts something like 52% at least with more than that being re-arrested for things. Heck, the death penalty hasn't even been shown to prevent other folks from murdering folks. Neither have absurdly long prison sentences, including life in prison.
