The Trolley Problem

[Polyedit2000]

I pull the lever. I might be wrong if I base this on some random Youtube puzzle, but if a lion is starving, it might already be dead whereas there is a risk that the five lions may eat one another and I'll have to deal with at least one fed lion.

A machine will tie you up from morning to sundown. If you pull the lever, the machine will instead tie you up from night till morning.
