[In the movie, Man of Steal, the pastor/priest tried to convince Superman that people were worth him risking his life to save. I don't think the priest made the case. Does history show that mankind has any redeeming value? Why would a person outside of the normal choose to save us at the cost of his own life?]
"Only 5% of the population is worth saving." How does know if they are one of the 5% worth saving?
"People are worth saving because we are part of humanity. If we don't save ourselves noone will." I agree that we do have a vested and personal interest in mankind being saved, but no matter how WE try, we seem completely impotent at saving ourselves. Marx proposed a system for making a perfect world, and look at what an ugly mess it turned into [i.e. Lenin/Statlinist Russia, China under Mao, North Korea]. The U.S. often comes off as if its choice of president will make a real difference. Yet, no matter who they elect, ugliness and hardship still exist rather than a beautiful, peaceful world. The process of people trying to fix and save mankind on their own power seems to make matters worse rather than better.
