Moussaoui wants to die. Let him have his wish. The arguments that this will make him an Islamic martyr will be counterbalanced by the humane way that we put such animals to sleep, as contrasted to the horrid demonic decapitations by masked men featured on Islamic videos worldwide.
Only if we bury him with a pig.
Otherwise, I'm wondering about the worst thing we could do to him, and it might instead be 75 years in deep, soundproof lockdown in one of those "hellblocks" where the noisiest and nastiest and most violent prisoners go, to be locked away with the sounds of their own voices and the bulletproof knowledge that nobody can see or hear them, and nobody cares if they live or die.
Condemning him to a prolonged, futile existence and denying him "martyrdom" might be tougher on him. But call me Pollyanna -- I'm just looking for the very hardest, most permanent way to screw him where it hurts his little fanatical ego the most.
I disagree. Let the bastard rot in prison for the next 50 years. I would feed him pork and anything else which is against Islam and not tell him for several years. It will save taxpayers money overall keeping him in jail. Death is the easy way out.
