This image implies that a decision tree could be made that is large enough to replicate the physical transistors, simplified as switches, as an abstraction of a reasonable processor, to determine how many people would die if you played DOOM.

Infinite people will die, the only difference is the ratio of how many people will suffer from the trauma of making that decision versus the people that died on the track…

I've always considered this an unsolvable problem but your image just inspired me.

If I leave one of the final levers in an intermediate position, is there any chance the trolley derails and not only gets the people on both tracks but also most of the ppl inside it & makes the next trolleys collide? I'm going for a max score here.

Yes.

Keep mitigating damage for as long as you have to.
