Think about how much it costs to incarcerate someone. Do we want them just sitting in prison lifting weights becoming violent and thinking about the next crime? Or do we want them having a little purpose in life and learning a skill?
It seems sensible to me that we should look to the medical profession that over the centuries has helped us to live longer and healthier lives to help us die peacefully among our loved ones in our own home without a long stay in God's waiting room.
