@Lulupab: Are these people willing - or am I dragging them to my facilities forcibly?
The danger from my end, comes with my opinion of the human race as an important species to the earth ecosystem. I will die, there's no arguing it or raging against it, and my concern for the continuation of the species is non-existent.
Stars burn out wiping out solar systems - black wholes drink large portions of galaxies - to think one species, sharing a blue spec with millions of other species, is somehow of some universally scientific value - doesn't really register to me.
So - would I "let" the human race go extinct. I cannot say that it would not be enticing. It's an invasive species that has, for all intents and purposes, put the other 2 million species on the brink of extinction. The virus is just nature trying to develop a vaccine for a disease endangering the whole.
What might coerce me - is that choosing their deaths, over the deaths of the supposed "sacrifices" is in equal measure wrong and greater measure due to the amount of beings who's free will I would be taking from them by allowing the virus to run it's natural course.
Whether or not I sacrificed your relative to stop the virus and save the human race from extinction... I would never, ever consider myself anything but a monster if I forced a group of people to die to save the rest. There would be no victory for me, no celebration, no excuses as to "why" I did it. I would likely seek seclusion and anonymity.
You can say I wouldn't - that's you're prerogative - but anyone who knew me knows I would never see a situation like this as anything but the "least horrible failure".
And that is NOT the same as: "Regrettable sure, but excuse excuse excuse... "
