Religion does no harm.
Faith is powerful enough to immunize people against all appeals to pity, to forgiveness, to decent human feelings. It even immunizes them against fear, if they honestly believe that a martyr's death will send them straight to heaven. Religious faith deserves a chapter to itself in the annals of war technology, on an even footing with the longbow, the warhorse, the tank and the hydrogen bomb. Believers all over the world do a lot of good in the name of their respective Gods and this should not be forgotten. U nfortunately, I believe that this good is far outweighed by the harm that can also be caused by such beliefs.
