Why don't you instead argue for summary execution? Seems like the natural conclusion to your points: * we gain nothing from locking them up, and it costs us a lot to do this * redeeming them might not work and if it does it costs us a lot * we don't want them around You could try to argue for shipping them to some island, shipping them to another country etc but there's some obvious shortcomings to this such as slave rebellion, other countries punishing through sanctions if you ship your criminals to them etc, so am I missing something or is the natural solution to your position, swift and summary execution?
