Ok, it seems people are doing it mainly because 'well, I'm dead either way'.
How about a twist on the OP, without wishing to hijack it...
Would you sacrifice yourself to save say, Europe, Australasia and the Americas?
If you had some miracle genetic strain and you were the only person who had the right makeup to defend against a new virus, but they had to kill you to harvest enough material to create the antivirus?
Turns out there's been outbreaks in America, France, and New Zealand, but they've locked down all international travel. So, the virus will spread slowly but uncontrollably unless you sacrifice yourself, but its some utopia where the government won't have you immediately carted off and killed.
I'd probably demand 24 hours of pure pleasure but then yes.
The object isn't to find some magic solution btw, its a simple would you die to save millions of people, even tho its a disaster that the human race could possibly come back from. Maybe once those continents had been scourged the human race could start to repopulate.
I'm already predicting a few 'well it'd probably be good for the world and humanity' posts already!
