The Moral Destination: Life's Four Directions

Counting the starting point, that makes the quantity to five "destinations." Why only four directions? Why not just two, or just one? What is the metaphysical cause for having these choices of directions? More precisely, what is the very nature of humanistic causality that gives rise to having multiple directions?

This meeting brings back the moral compass (Jul. 26 (https://www.meetup.com/The-San-Diego-Philosophers-Roundtable/events/73595182/)) that began our discussions on metaethics. A compass serves as a means to some end. How many primary ends are there (Dec. 6 (https://www.meetup.com/The-San-Diego-Philosophers-Roundtable/events/93462232/))? How many compasses are there?

The bonus question to ask, if we finish early, is, what determines a question about life to be classified as either a metaethical question or else an ethical question?
