Well, I have one good reason, because he will be a martyr for his bloodthirsty moon g-d.
I think the best alternative to killing him is the following:
1. Cut off his hands and feet, let him live life as a involent and cripple.
2. DUmp his face in acid, so he is permanently deformed and ugly.
3. Lock him up in solitary confinement
4. Feed him diet of pork trimmings, dead rats and bread.
5. Invite him to read the bible/Torah.. Maybe he will realize his child raping moon g-d is not really a G-d?
6. Torture him daily, until he rejects allah and admits his Prophet was a child raping pedophile , murder and thief.
7. Force him under torture, to give names of all terrorist assocations he knows.
8. We should televise him eating pork, calling Mohammad a child rapist and the beatings.
9. Display him on television and mail the videos to all middle eastern countries, to let them know how we reward their martyrs in USA.
To me, this would be a much better punishment, then some pathetic lethal injection. WHy should he die peacefullly?? He should be tortured forever and ever, for being the bloodthirsty baby murderer he is!
However, if we do not do what I have spoken here, then I think these are the proper forms of execution:
1. Death by firiing squad, first using small caliber bullet to shoot his kneecaps. WHen he is screaming in pain, finish him off. Like what they did with Che Guevara.
2. Death by hanging.. No blind fold! Let the families of those who were murdered be able to give him a slap or hit on the face each, before he is hung.
3. Throw him into a cage of hungry coyotes. This is a gruesome way to go, very dishonorable toa muslim to be masscared by a pack of filthy dogs.
4. Electrocute him slowly. Dying in the electric chair is nasty, eyes pop out, head melts and turns into ash. Don't give him any painkillers, let him feel the electricity boil his organs.
Anyway, I hope nobody is mad about my thoughts, this is just what i think is the best punishment. Capital punishment is not always a great solution, when alternatives exist that are far more far reaching.
