Death for Moussaoui?

Now that Zacarias Moussaoui has been found guilty, the jury must determine whether he receives the death penalty for his role in the September 11 terrorist attacks.
My vote would be no. Moussaoui was willing to sacrifice his life in the attacks. Putting him to death would allow him to be considered a martyr for his cause. Instead, let him rot in prison for several decades, or choose to end his own life in a true showing of cowardice.
