Nah, they’re not there for rehabilitation, they’re there because they’ve proven themselves completely unable to exist in society and so we choose to remove them permanently from it. As we are not monsters, they would be provided with a modicum of comfort and entertainment but they will never breathe fresh air, see the sun nor speak to anyone else ever again (other than staff in the case of medical or mechanical need). This is punishment, but also protection - sometimes it seems that we have forgotten that the law-abiding citizens deserve to be protected from the monsters that do nothing but prey on them and seemingly care not whether they are caught and caged, prison for those individuals stopped being a concern a long time ago and simply became “the price of doing business”.
