I've been trying to figure out why parents are so likely to toss out the "I would torture to save my own little boy or girl and you're a weak and worthless would-be parent if you would do less!" defense of torture. I think I've figured out why this is plausible to us.
In a culture in which our morality flows only from our own personal commitment to that particular ethic, there is nothing more beautifully self-immolating than giving up your own morality for the sake of the kid. Dying for your child means only giving up your life. Breaking your own moral code for the sake of the child means giving up something closer to the center of your being for the sake of your kid, which is so much cooler.
