Would you do it or not?

the world is overpopulated, so . . . .

It's a win win

Deal

With any luck it’ll be me

As long as my family/friends are immune, I'm game.

...do I get to pick who dies?

If he dies... he dies.

Yup

It's a tough world out there. I mean I have to survive.

Do you want the entire world to die?

Yep. 100%. Does that make me a bad person?

*signs a contract for a mansion* *thousands of people mysteriously die*

Roughly two people die every second, 105 people die each minute, 6,316 people die each hour, 151,600 people die each day. A person dying for every 1k I spend would change nothing merely nudging the ultimate cause of death if not the exact circumstances.
