Capitalist solution: Which ever of the two lever people that has the most wealth gets to pull their lever. The other gets a payout for their loss but only if their wealth is within one standard deviation of the winner.

i’ld rather press shift-tab, go to steam library, push stop and then the uninstall button 😉

There’s no way you can redirect the trolleis on those tracks. They’re not really interconnected. So the problem is only theoretical - no matter whether you pull the lever or not, the trolley will continue on it’s journey to kill your relative.
