Yes, you have to choose the end goal but then you can use rationality. I'm not sure how you choose a good endpoint. Maybe "life is good" and therefore "expand life". This could lead in many ways though - from fascism to reversing entropy to human experimentation. It seems most morality for all humans comes down to "what is best for my in group" and then a selectively defined endgroup. There may be an argument for objective morality being based on expanding knowledge of the universe to the point where we may discover morality? We have very little accurate data on the universe and life in the universe to draw on - maybe as we gain a more accurate and useful model of reality morals will come out of the"woodwork" like writing allowed us to begin pontification on them across generations.
