The amount of care I hold for people I don't know is so low it cannot be measured. I seriously don't give a damn about random strangers.
Since I don't give a damn, and there's no penalties that would be levied, why should I give a shit if dude lives or dies? And the 750K I'd net for doing it(loltax) would buy a plot in Nevada, pay a crew to build a bespoke house, pay for myself and my love to move to said house, buy us a couple of small sports cars and a resto on my truck, pay for my college, and pay for living expenses for about two or three years while we find jobs we genuinely enjoy.
So yeah, in the situation the OP posted, there's no reason for me not to pull the trigger.
How would you feel if you were on the other side of that button?
