I'll be called evil or ignorant or this, but if my child has to suffer to save others, that is something I am willing to accept as God's plan. It is important that we give of ourselves to each other to maintain our existence. If my child is selfish enough to never do that and he becomes one of those "evil people", then at least, if God so determines, his life would not be wasted if it is used to benefit others. I believe this is only a problematic idea when people try to take the determining of whose is evil into their own hands. Then we are behaving selfishly instead of trying to focus on and better ourselves, and that is why we cannot progress as a society. If people behaved as though a hypothetical God would have them do, then that would help us. It would be crucial, however, that the concept of that God were based on love, joy, self-control, kindness, peace, patience, goodness, gentleness, and faithfulness; not ourselves as God, which many follow.
