If you kept an innocent man imprisoned for the remainder of his natural life then you were a thousand times more cruel than had you executed him. I would prefer death over rotting in prison hoping to find the last shred of decency in the american judicial system that had already imprisoned me. All of your arguments are romantic and foolish.
There’s no experiment necessary in proving nitrogen as a silent and painless killer. Scuba divers have done all of the experiments for us, mostly by accident.
Imprisonment is barbaric.
If someone has done something so bad that they should be locked up for life then they should be dispatched not kept as some kind of morbid pet of the state. If you murdered a bunch of people (mass killing of serial style) you need not waste any more of our air. If you rape you should be killed too. If you’ve gotten yourself on death row fuck your rights.
Ah, but it doesn’t have to be. There’s lots of inexpensive, humane ways to dispatch a human. How methods like electrocution and lethal cocktail injection were decided on is difficult to understand. Nitrogen, though, is probably the nicest way it could be done. Relatively cheap too, and with zero chance of failure.
So there’s gnome or money in the machine?
