Besides the absolute inhumanity of mass genocide, your comments rings of hyperbole unless you are willing to lead the charge by offering your own life before anyone else's.
"the absolute inhumanity of mass genocide" - If your focus is "survival of humans as a species", what's so "inhumane" about it? You are focusing too much on the individual human and not on the species.
And of course I wouldn't sacrifice my own life first, since from my perspective that's obviously the most important thing and everything else is secondary. But once my life is preserved, I look at the bigger picture and see that we (I) would obviously be better off if we killed off 50% of the remaining population.
Why is that so hard to wrap your head around? I'm fairly sure you would see it the same way (if you would just admit it to yourself).
