@ Jesus = hippie: suicide bombers take the lives of others, whereas I was referring more to giving it for the sake of saving someone else.
@ all: great responses! Keep them coming - I think that it's very beneficial to discuss such deep, private issues in the public sphere.
My answer: I would mainly give my life fighting for the truth, or 'the cause' - but that would be my own cause, not some religious mantra.
In other words, if I would be thrust into a situation where I would need to take a principled stand based on what I know is right - for me, my family and children, the rest of humanity, in that order.
I would take that stand, and if I'm killed during such a stand, i would go gladly and consider it an honorable death that others could look to as a positive example.
Of course, I would also give my life for my loved ones and some friends - but depending on the situation.
