I personally have always voted for the death penalty because I believe that people who go out prepared to take the lives of other people forfeit their own right to live. I believe that that death penalty should be used only very rarely, but I believe that no-one should go out certain that no matter how cruel, how vicious, how hideous their murder, they themselves will not suffer the death penalty.
But secondly you say 'society must exact vengeance, and society must punish'. Wrong on both counts. Vengeance comes from the individual and punishment from God.
We should find ourselves committed to killing a great many people whom we now leave living, and to leave living a great many people whom we at present kill. We should have to get rid of all ideas about capital punishment.
A material resurrection seems strange and even absurd except for purposes of punishment, and all punishment which is to revenge rather than correct must be morally wrong, and when the World is at an end, what moral or warning purpose can eternal tortures answer?
One whose troops repeatedly congregate in small groups here and there, whispering together, has lost the masses. One who frequently grants rewards is in deep distress. One who frequently imposes punishments is in great difficulty. One who is at first excessively brutal and then fears the masses is the pinnacle of stupidity.
