If i had some idea of how I was going to fix everything, then I would have to preserve myself. If I knew I could fix everything the others and I had done, I might be worth more than five other people. As it stands now, I am no more valueable than one other person, and am in fact, less valueable and more destructive than many others, and so, it would be okay to make the sacrifice. If you are truly good though, you should choose to save yourself because the world needs you, and there is a much greater than 1 in 5 chance that 5 random people are destructive these days. Thats nit to say they are really bad, its just that there are so many people, and almost all of them depend on a system that is consuming much more destructively than productively.
