The Saudi Crown Prince orderer of the torture murder beheading dismemberment of a journalist named Kashogghi is a prime example. He should "enjoy" the same fate as he ordered for the journalist.
All pedophiles who torture rape murder their victims. They should also be gifted with the exact method of dying. Just so they can personally enjoy what they inflict.
Those are the top two that come to mind. What other perps deserve to "enjoy" the exact same fate they decree for their victims? Any ideas?
