We all benefit from a society with a higher floor for suffering. We all benefit from a society that doesn’t see hurting people unnecessarily as justice.
I am not a prisoner, I hope to never be one, but if I find myself forced to violate laws to sate my conscience I hope I am treated as kindly as possible, so for that to happen I must demand we treat even the absolute dregs of society as fellow human beings who can reform and don’t deserve unnecessary suffering.
