I think that it should decide which ending you get based on your decisions regarding your enemies throughout the trilogy (like, did you spare or kill the Rachni Queen, save or destroy Collector Base, rewrite or delete the Heretics, cure or sabatoge the Krogan, save or kill the true geth, and any others I may have missed) instead of basing it off your morality, because the endings don't really have a "good" or "evil" feel to any of them. If you Destroyed most of them, you get destroy, if you spared most of them, you get Control. And while I think that Synthesis is an awful ending, I think it should be unlocked through a combination of sparing destroying and it's required that you achieved peace between the Quarians and geth, and achieve a stable krogan future as well. I also still think it should be possible for Shepard to live, just extremely difficult to achieve.
