“First, he has already survived one execution attempt”
This would not be an issue with a firing squad or a an old fashioned hanging.
Or drawn and quartered. Or burned at the stake. Or....
Or a Gamma Ray Device. Instantaneous death of every cell in the body...............
I remember seeing a demonstration of the effects of the ‘Neutron Bomb’ back in the 70’s when it was in development (actually it already had been developed by that time) when Carter killed the program.
They had a Rhesus Monkey in a cage in front of a box about the size of a clothes dryer. There was a circular opening on the front of the box that was closed by means of a iris like a camera’s shutter.
The monkey was moving around on a limb in the cage doing what monkeys do just looking around like normal.
Then someone activated the shutter and it opened and closed just like a camera shutter in less that a second. There was a flash of light and the monkey fell over dead. No sound, no jerking, no pain because every cell in that monkey’s body was dead. ..................
