The Supreme Court "gets" religion

I listened to the NPR coverage this morning on the Supreme Court's decision with regard to Dubya's Guantanomo tribunals, probably the only true "victory" the current Court has or will grant that respects human rights.

But the decision sort of missed the point with regard to the absolute futility of torturing prisoners, specifically those of Islamic faith.  (From here, I'm mostly conjecturing, but bear with me.)

The core belief of a religion -- whether Judaism, Christianity, Buddhism, Islam -- is that [the applicable] god will protect and sustain adherents through life's trials while promising absolution and forgiveness in death.  The torture rendered at places such as Guantanomo and Abu Graib becomes life for the prisoner victims, another inevitable trial to be endured by the faithful.

So the question is:  Why haven't these government and military yahoos figured out that true believers will endure any hardship for the ultimate goal of eternal absolution?  Is it because Christians (and Compassionate Conservatives) have their own limits and know full well that, in similar circumstances, they would sell their own souls to achieve immediate relief?
