I do not think that’s something fictional. For instance, if that person is your child, it will be too much agony to make a "wise" decision. There is no judgement here for whatever choice to be made. It’s war between conscience and heart. My point is that when the 5,000,001 are people irreverent to your life, the choice is quite easy to make; but when there is attachment to the one to be given up, the pain of loss or even the thought of murdering is unbearable and life-long. We cannot love our neighbor like we love ourselves. That’s the reality....
