Double Standards and Guilty Bystanders

It would be quite ironic if Zacarias Moussaoui is put to death because he had prior knowledge of the 9/11 attacks but failed to inform US authorities.

Isn't that exactly the same thing as Bush did?

And isn't most of the USA also guilty of standing idly by while Bush's massacres in Iraq have been committed? While prisoners have been raped and tortured in Gitmo and other US gulags?
