It’s like the trolley problem but one side of the track is clear. But the concept is now so deeply engrained that some people still object to the idea of pulling the lever.
If this was a trolly problem, one side would have several million deaths, there's a lot of switches we can activate at any time, and we're not entirely sure how many people are on each of the other tracks just that there's not many before the bend in the line that takes it through a thick dark jungle of our ignorance.
