Opening its argument that Zacarias Moussaoui be executed, the government asserted that he "did his part as a loyal Al Qaeda soldier" and caused the deaths of nearly 3,000 people by failing to tell what he knew of the Sept. 11, 2001, attacks.

Moussaoui pleaded guilty in April to conspiring with Al Qaeda to hijack planes and commit other crimes. The trial will simply determine Moussaoui's punishment, and only two options are available: death or life in prison.

To obtain the death penalty, prosecutors must first prove a direct link between Moussaoui and the Sept. 11 attacks. Moussaoui denies any connection to 9/11 and says he was training for a possible future attack. Read more.

Check out what FOX Fans are saying:

"I think that all prisoners should be granted life, unless they are too dangerous to keep alive. This man is definitely too dangerous to be alive. We must kill him to insure our own security." — Joshua (Nelsonville, OH)

"If I were on the jury, this scum would definitely get the death penalty. And I would also recommend he be put to death ten minutes after the guilty verdict. That’s more time than those people in the towers were given to contemplate their death sentences." — Bob

"Off with his head!" — Randy (Fort Worth, TX)

"I think he should be given life imprisonment without ANY chance of parole. I also think that if he wants food, shelter, etc. from the U.S. government he should have to work for it. I think there is a lot to learn from keeping him alive and handing him over to our intelligence agencies for further 'examination.' He is far more useful alive than dead." — Thomas (Atlanta, GA)

"He claims to be proud of all the actions he has taken as a terrorist, I will be proud of the actions that this jury takes. If he gets the death penalty, then fine. If its life in prison also – good, provided that he is not allowed to come in contact with another human being for as long as he lives. He has forfeited his right to claim that privilege. If I were on the jury I would vote for the death penalty." — Milt (Chelan, WA)

"Where are all the supposed pro-lifers now? Their logic is don't kill an unborn baby, but an obviously disturb individual is okay to kill. I don't remember reading about Jesus preaching conditional love and respect for life. Typical hypocrites." — Dale (Portland, ME)

"This trial is a joke. He has confessed to wanting to harm the U.S. There is NO proof that he has. It is just the mob mentality of a witch-hunt. If you think burning this buy at the stake is going to make things okay and make sense of it all, you are in need of much help." — Lisa (Brooklyn, NY)

"Kill him, but do it quickly. He should be thrown from a plane without a parachute. There’s no sense in wasting taxpayers' money to keep this terrorist alive." — Corey (New York, NY)

"I honestly do not believe that he had anything to do with 9/11. There are far too many holes in the case. How in the world could he receive a fair trial in this country?" — Kip (Wellfleet, MA)

"If anyone has ever deserved the death penalty, it is Moussaoui." — Virginia

"Death for this guy. He’s beyond rehabilitation." — Curtis (Mason City, IA)

"In 2001, FBI Director Robert Mueller admitted that the identity of those involved were 'in doubt.' He later admitted that there was 'no legal proof to prove the identities of the hijackers.' There’s no proof that the hijackers were members of Al Qaeda, or that they were even on the plane in the first place. Where is the concrete proof? If we were lied to about the hijackers, why wouldn't be we lied to about Moussaoui?" — A.J. (New York, NY)

"I would send him to his God. As long as he is alive he will try to recruit new terrorists in prison." — Bob (Fallbrook, CA)

"What use is there in killing him? I think he should be turned over to the CIA and cut off from the real world. He should be given the bare essentials needed to live and then be used to help win the war on terror." — Larry (Chicago, IL)

"I'd give him the death penalty without reservation. The man is proud to be partially responsible for the death toll at the trade center. He is a rabid dog, and like a rabid dog he needs to be put down." — George

"Death to Moussaoui. We must send a message!" — Paula (Houston, TX)

"I think he should receive life because his death would send a message that I do not think would benefit us in the long run. His death would only add fuel to the fire." — Lisa (Seattle, WA)

"This trial is a farce and pathetic. It saddens me that our government has continued to lie and let us down, especially the victims and their loved ones. This is all they have to hang their hopes on? What about the truth of what happened on 9/11? What about Usama bin Laden? Why have we not captured him yet? Why have we let Bush get away with dragging us into the quagmire of Iraq and fail to deal with Usama bin Laden?" — Justin (Miami, FL)

"I would vote for the death penalty. If eleven others were like me, we would only need the time required to fill out the paperwork before we rendered a verdict." — Marcus (Choctaw, OK)

"No doubt about it, death. He will only become more of a problem in prison." — Dorothy (New York, NY)

"Moussaoui should have been in the ground a long time ago. Likewise every other terrorist." — Walter (Bismarck, ND)

"Without doubt. I would also do it right away and not spend thousands of tax dollars with appeal after appeal." — Tom

"He is not guilty of the charges. He could in no way have prevented 9/11. Those events were set in motion without him. The government is doing a poor job not only in their so-called war on terror but also in the prosecution of terrorists. We need new leadership and a clear vision that gives us and the victims' loved ones justice." — Ken (Pittsburgh, PA)
