Would you sacrifice your child to save the world?

Your child is attacking a scientist who’s just discovered a cure for every disease. It will eliminate untold suffering for all humanity. The attack from your child against the scientist seems justified because the scientist is about to shoot your child’s spouse for destroying his data. Your child is honorably and genuinely defending their spouse against the attack of the scientist.

You, on a hilltop with a sniper rifle, have one shot. You know the entire truth of the situation. Your shot will definitely kill, not maim.

Who do you shoot?

shooting yourself won’t solve anything except your own dilemma… not an option
