| The Death Penalty is morally defensible in cases where the justice system is so flawed that the criminal would be likely to escape and cause more harm to society if allowed to live in a prison. (not applicable in mostg western countries) I also see it as defensible in a case where it is not possible to give the criminal due process (say, a battlefield) and releasing will cause great harm.
