Personally, I was a little upset with the ending when I finished the game. However, given some time and reflection, and looking at the various endings I think that there is a lot of good in each possible ending and each ending provides it's own moral challenge. This moral challenge is something worth talking about in my opinion and it's something that people who haven't played the games should have a chance to talk about as well. To that end I'm going to do a quick summary or "The story so far" to get you up to speed.
"The Story So Far"
In the world of Mass Effect humanity is far from alone in the galaxy. There are dozens or alien cultures that humanity shares the galaxy with and humans are essentially the new kids on the block as they have recently discovered the mass effect relays that link the various world of the milky way galaxy together. Mass effect relays are massive contraptions floating in space that are used for near instantaneous transportation from one relay to another. Nobody knows for sure where they come from but they are thought to have been left by an extinct alien race. Turns out they were built by a race of synthetic capitol ship sized robots called reapers that come every 50,000 years and harvest (kill them and build a new reaper based on the characteristics of that race) the advanced races of the galaxy, leaving the developing races in place.
ME1 is about discovering this threat and stopping the awakening of the reapers. ME2 has a similar theme of stopping them from coming but in ME3 they have come and despite uniting the whole galaxy against them there is still no hope in winning in a fair fight. Enter the crucible, a design for a weapon passed down for countless 50,000 year cycles that is improved upon by the previous generation before they are ultimately harvested. Theoretically, it's supposed to destroy the reapers but nobody knows for sure what it will do. In the ending moments of ME3 you have activated the crucible and have a decision to make.
Paragon vs Renegade vs Neither
It's worth mentioning at this point that you have been presented with hundreds of choices by this point and there are roughly three possible answers to a question. You can do the Paragon thing (my personal choice) which translates into, "Doing the right thing without compromising honor or morals." Renegade is more about "Getting the job done, consequences be damned" and finally you can choose to not use paragon or renegade conversation options, resulting in more depressing and more realistic results (not being able to talk someone down before they start a losing war, not being able to save all your friends during a suicide mission, etc).
It's also worth mentioning that there are a couple of important themes in ME3 that play into your choice. The first is the struggle between artificial or synthetic life and organic life. Once of the races in ME are the Geth, a group of sentient robots that have been at war with their creators for 300 years and have worked with the reapers out of fear for their lives. In ME3 you have a chance to end this conflict and negotiate peace, heck they even are there at the end helping you. Additionally, over the course of ME2 and ME3 you are introduced to EDI, an artificial intelligence program that achieves sentience and a body during your adventures. She even starts dating one of your crew members and is considered a friend of the main character.
The other theme worth mentioning is indoctrination. The reapers are like robotic Cthulhus and are almost god like. Their mere presence can influence people's thoughts and indoctrinate them, turning them into unwitting allies, resulting in setting their enemies against each other. One such person was convinced right up to the end that the reapers could be controlled and that by doing so, humanity would enter a new golden age.
The Final Moments and the Three Choices
In the final moments of ME3 you have activated the crucible and you meet an AI that claims to control the Reapers. Apparently, the Reapers are this AI's solution to the conflict between artificial and organic life and that by "pruning" the galaxy every 50,000 years, it feels it is preventing the eventual extinction of organic life at the hands of synthetic beings but it says this solution has failed as evidenced by your presence there. This at least explains why the reapers didn't just blow the crucible to hell, as it was some sort of test but I'm not sure how much trust to put into an AI that claims to control the Reapers. Granted, Shepard has been blown halfway to hell by this point, many of her friends are now dead and she can see the grand alliance being torn to shreds just outside the viewports so she's not in too much of a position to argue.
You are then presented with three choices, Red, Blue and Green, all of which will destroy the mass relays, effectively setting galactic civilizations back thousands if not millions of years:
Red (Renegade)
The red option is to destroy all synthetics in the galaxy. At this point Shepard is more machine than person so it's quite possible a fatal option for her as well. For a Renegade Shepard, they've probably already killed off the Geth so really they are just faced with killing themselves and a friend to save the galaxy (for the moment). However, the AI warns that the cycle will eventually repeat with synthetics and organics fighting again. For a Paragon Shepard this is a much harder choice. You are essentially asked to destroy two entire races, one of which is determined to destroy you (the reapers) but the other (the Geth) are recently incorporated allies. What's more, you just had a friend sacrifice himself (Legion) to give the Geth intelligence on an individual level (they had to network to achieve this in the past).
Questions:
Is Xenocide an acceptable option in the face of an enemy that will not stop and is in the process of committing Xenocide on dozens of races simultaneously?
Is it acceptable to perform Xenocide on the enemy and an ally? What about killing yourself? A friend (without asking them)?
Blue (Paragon)
The blue option is to kill yourself and transfer all that is you into the Reapers and control them. This presents some interesting moral quandaries. First of all, your character has been convinced that the Reapers could not be controlled and, in my case, talked a man into shooting himself in the head to stop him from trying. Granted, he was indoctrinated but still what do you say to him if you meet up in the ME equivalent of an afterlife... whoops, guess you were right? Also there is the question of taking away the free will of an entire race. The Reapers obviously despise organics and Shepard is just going to make them all model citizens? Remember, the Reapers are sentient beings, although they appear to have been reigned in by another AI.
Questions:
Is subverting the free will of an entire race an acceptable way to stop them from committing Xenocide multiple times?
Is it better or worse than committing Xenocide yourself?
Green
The green option is the bullshit option (in my personal opinion). It's about as close as you can come to a happy ending but I personally feel it would result in anything but a happy ending. In the green option you kill yourself to combine synthetics and organics into a "new DNA" and everyone becomes an organic synthetic hybrid. According to the AI that controls the Reapers, this is the "final evolution" and it'll solve all those nasty problems with synthetics and organics killing each other.
There a few problems with this line of thinking (putting aside Biology). First of all, the Reapers, who despise all organics, will become part organic and then what? Are they going to do a bit of soul searching and see how wrong they were? Will having fleshy bits make them see organics really aren't that bad? Or are they going to go on a rampage and kill everyone? Also, I'm pretty sure everyone in the galaxy can find something different about each other to kill and be killed for. Finally, what stops people from creating purely organic or synthetic beings? Then you'll have three participants in a galactic drama, won't that be fun.
There is also the moral implications for this. You are altering the biological basis of everyone in the galaxy without their permission. To put this in perspective. What if a scientist found a way to convert everyone into white women that could reproduce? Or Asian men? Would that really solve our problems? Or just create new ones?
Questions:
Is it morally acceptable to alter the genetic code of all sentient beings to prevent Xenocide?
Would it even work?
When first presented with these three choices I actually stopped and started making a pro's and con's list. I eventually chose the blue ending but am unsure if I made the right choice. I'd say that classifies as a perfect ending to this series that has been about choice and morality. Hopefully, this leads to more discussion on the issues presented in this series. I'm also curious as to which choice you made (or would make) and if you feel like it was the right choice.
