You've thrown this OP onto at least three other boards and I don't see that it sparked much debate. Didn't really get into the issue of kill or cure.
If you're looking for something to counter the believer claim that God can do whatever he wants because he's God, then you need a better OP. Especially since you already granted it as truth for the sake of this topic.
Scripture comes in handy when supporting claims concerning God.
As written, I don't see this as good discussion material.
