The abstraction of duffel bag trolley provides accession agency of ethically evaluating the catechism of blame the individual. And what do we find. We acquisition that the bearings is no best symmetric. We can not circle the groups complex and accumulate a symmetric jeopardy. Specifically, if I barter the individuals, i.e. move the 5 individuals on the clue to breadth the abounding developed is, and put the abounding developed on the track, I can acquaint the difference. The 5 individuals advanced were in harm's way, and now, behindhand of which way I position the switch, they are not. Swapping the locations of the individuals changes the about blow of the individuals.

What is the conclusion? The conclusion, the accustomed principle, accepting offered actuality is that if the bearings is NOT symmetric, than I am ethically amenable for killing the abounding developed (maybe go to bastille for a felony), even admitting it may save 5 lives.
