Re: a question…
Peace CM
I hope you are Muslim because this reply will hopefully bring your concern home. The only criteria for right and wrong should be viewed by what we are revealed about right and wrong through our holy scripture. Whether the world views numbers of deaths as more or less of a travesty is another debate and in fact an easily defeated one with sound reasoning.
I, like most Muslims will default to the superior motive of the value of a single life as though it is worth the whole of humanity only then can true justice come about in the world.
Now for justification …
Because of that We ordained for the Children of Israel that if anyone killed a person not in retaliation of murder, or (and) to spread mischief in the land - it would be as if he killed all mankind, and if anyone saved a life, it would be as if he saved the life of all mankind. And indeed, there came to them Our Messengers with clear proofs, evidences, and signs, even then after that many of them continued to exceed the limits (e.g. by doing oppression unjustly and exceeding beyond the limits set by Allah by committing the major sins) in the land!.
