Well considering the outcome is the same no matter what, it becomes a question of how will you live your life as the lever puller? If seeing the trolley do a sick loop will bring me joy, then certainly the best choice for me in that moment would be that one. If I would rather embrace the pain of five people dying sooner rather than later and just get on with life beyond that, then that's the best choice. So there's really no right or wrong answer. It's simply a choice to make based upon one's preference for living.
