If a person is convicted of a brutal crime why is it cruel and unusual punishment to do to them what they did to the victim?
For the sake of argument- there is no doubt of the guilt of the offender. Also assume that there are those willing to inflict the sentence, possibly even allowing the family or victim to take part or decide.
Would such a policy in any way deter violence?
