Wait, so your problem isn't that the ending(s) don't suit the game but a moral stance?
Classic sci-fi very often has lose/lose endings
Exactly. That's my point. It didn't really surprise me that a sci-fi series came down to a tough choice. Well, okay, it did surprise me the first time I played through, of course, but it didn't ruin the story for me. Facing an impossible foe, Shepard is forced to either let all advanced sentient life die (do nothing), or defeat the enemy in a way that's not a total win for anyone.
Honestly, I still don't see your problem with the green choice. Humanity will most likely move to integrating synthetic with organic over the centuries to come, especially in the Mass Effect universe, so I don't see any real problem with hastening it in order to stop the Reapers and put everyone on common ground. Seems like a pretty good compromise to me. A no-brainer when I played my Paragon Shepard.
It makes Shepard the greatest war criminal in history,he dwarfs all others in history put together. If you have no problem with someone either killing,enslaving,or forcing people to become members a race then I don't know what to tell you. As I said all stories come down to basic moral choices and the fact that Shepard makes his based only on the facts giving to him by the person who created the reapers makes it even worse. The fact is the message of the series is now that different races can not get along in any way and the only real world solution is to wipe out or enslave everyone who is not a member of your race and the only other answer is if everyone because members of the same race. The endings may have well have been written by the KKK or the NAZI party. It's the sort of sick so called choice but belongs in our past. In fact in the story it self it feels like Shepard only makes the choices because he is dying and wants to take everyone else with him or at least leave them in chains,how is that not evil.
Let me put it this way if the story was set in modern times and it was about a race war between black and white Americans and in the end in the hero who was dying choose to either Enslave all black people,force everyone to become white,or kill all black people with magic would you really not have a problem with that. Like I said all stories boil down to their moral choices and the ones at the end of Mass Effect 3 make me sick they are the sort of thing that only makes sense if you buy into the ideas of the KKK and Nazis and every other race based hate group out there ,I have said this many times before but people can't be bothered to read because it is easier to mock people for wanting a happy ending. I am fine with everyone dying as long as they dying fighting for something that is not Hitler's wet dread. The ending of the game sends a message that racism is okay and I know most gamers don't have a problem with that so I am sorry that I offend you but I do. Sorry but I believe what a story says and the ideas it promotes are important.
Since no one else seems to agree with me or have a problem with this I am just going go and avoid anything with Bioware,EA,or Casey Hudson's name on it from now on.
