But this isn't a cycle of conduct. Criminals don't go on to reoffend because they're trying to get back at the state. They are punished because they violated the standards of conduct established by society. Their choice to go back to that conduct has nothing to do with being punished, it has to do with their own wishes and desires. The whole point of any criminal or civil penalty is threefold: to protect the public, to punish the criminal and to rehabilitate the criminal so they don't re-offend when they are released. All three of those points must be true for imprisonment to be appropriate. If the individual is not dangerous to the public, they have no business being in prison, they should be handled civilly. All penalties are punishing, so that's pretty automatic. If they are never getting out, then there is no reason for them to be in prison in the first place. We ought to put all LWOP criminals to death and clear their cells. They aren't getting out, why keep them around?
