Now that I have your attention with the clickbait thread title....
After a certain level in the game, you find out a fact about the origins on the Angara.
The fact that they were bio-engineered by the Jaardan.
Later on, Suvi tells you what a horrible thing it was, and Ryders options were limited to;
1) Yes its bad.
2) Yes its bad.
I rolled my eyes a bit at another example of SJW preaching & carried on with the game.
Lets make it clear though - slavery is bad when you apply it to earth. Treating a living, breathing, self aware person as a thing is bad, especially when that person doesnt want to be a slave.
But then I started to think about it, and I got annoyed at the blinkered approach to an interesting question.
How can we have the arrogance to apply our beliefs to a race far more advanced than us, about which we know practically nothing? Maybe the Jaardan were a right bunch of evil buzztards & created a sentient, self aware race that they oppressed as organic slaves, but maybe they didnt.
What technogically advanced race is going to be stupid enough to create untold millions of self aware, sentient beings who might rebel & overthrow them?
What if it went like this. The engineers go to the Jaardan supreme leader & say "Boss, we have found a way to create organic tools. No Jaardan will ever have to work again, risk their lives in war, do the dishes or laundry, will you authorise it?"
If I was the leader id say "Bloody hell, I will be the most popular leader in history, my people will love me for ever". Then I would say "What if the slaves overthrow me & my people you dumb engineers?"
The engineers say "Sorted boss, the slaves will be genetically programmed to love their jobs & serve us. It will actually make them happy & content". "Do it!" I would reply.
We wont know why the current day Angara have free will, maybe the engineers made a mistake, or the Jardaan set them free, or they simply evolved.
But if an organic being is created by another being & has no concept of freedom & loves its role in life, is it our place to criticize said creators?
If we create AI's to serve us, & we program them like the Jaardan programmed the Angara, are the AI's slaves? Are WE slavemasters?
An interesting moral quandary, totally avoided in ME:A, because we are forced to say "Slavery is BAD, m'kay".
