I am certainly not against having a prison system. There are always people in society who will do wrong things and society should both punish and help them. Yet if wrongdoers repent then they should be given another chance. If you have murdered someone and tomorrow you are going to be executed, you are still a "human being" to day.
我並不是反對有監獄制度，社會上有些人犯了錯，社會應該懲罰他並且幫助他；作錯事的人悔過，就應該給他生存機會，就算你殺了人，明天要槍斃，今天還是個「人」。
