Imagine an iron house without windows, absolutely indestructible, with many people fast asleep inside who will soon die of suffocation. But you know since they will die in their sleep, they will not feel the pain of death. Now if you cry aloud to wake a few of the lighter sleepers, making those unfortunate few suffer the agony of irrevocable death, do you think you are doing them a good turn?
