And the scripture showed that there is more than one death -- a second death -- so there is a capital punishment being administered when someone is "cast into hell".
So, is God wrong to administer capital punishment?
You seem to insist that I adopt your interpretation of what eternal separation from God is and why, when I and others here have already explained our interpretation of that is different than yours.
Jesus is without sin and He did not cast a stone at the woman caught committing a capitol punishment offense.
Are you or anyone you can name without sin and therefore worth to throw the first stone in executing someone?
