Death Penalty is government sanctioned punishment by death.
Yep, death. Terminal. No chance for redemption or reformation.
The crime is judged heinous enough to be deserving of nothing less than death for the person that committed, or allegedly committed, the criminal act.
Jesus was subjected to capital punishment.
Thankfully, He defeated even that.
Hosea 13:14 (KJV)
I will ransom them from the power of the grave; I will redeem them from death: O death, I will be thy plagues; O grave, I will be thy destruction: repentance shall be hid from mine eyes.
