This has probably been brought up a hundred times, and I've just never seen it.  So, if that's the case, I'm sorry.  Here we go: 
 
Okay, so I played through the game again recently to set my story up for ME2.  But, as I'm playing it, one thing bugs me: Saren.  Now, the Geth are a strange combination of organics and machine (cyborgs, if you will), and this is what makes them so interesting and feared in the ME universe.  At least, this is what I've picked up.  Then, here comes Saren.  He murders another Spectre and makes the council think he's not evil...but the dude is HALF MACHINE now.  How is this not mentioned or brought up?  How do the council not notice that "Hey, this guy's got wires sticking out of him now, and he's got robot eyes."?  It's VERY obvious.  Even on his hologram when he's being questioned by the council, you can tell that the guy is no longer totally organic.  This has been bugging the hell out of me.  Does anyone know if this has been addressed?

Nobody knew what Soveriegn was or was capable of, and I don't think the coucil would ask a Spectre about what may just be cosmetic changes to their looks.

The process to make him mechanical was definitely gradual, and at the council meeting they just probably didn't care.

Just look at a lot of the gear that people are running around with in the Mass Effect universe. Saren having some cybernetic enhancements does not make him something to be suspicious of. Especially since he's one of the longest serving Spectres. As for the Geth I don't recall them ever being shown to be cyborgs. They are straight up sentient machines whose intelligence is proportional to how many are together in one place. They arn't something like the Borg who require living beings to "reproduce".

I think that in the ME universe, these kinds of implants are kind of regular. All biotics have implants in their head, and if Saren is above all forms of the law because he's a Spectre, he can probably do whatever the hell he wants to his body. I don't think the council questions him, especially after knowing all the good things he's done for them.

I don't think characters in the Mass Effect universe automatically associate robotic parts / cybernetics with evil. I think even one of your item slots for each character is some kind of cybernetic implant. I would assume Saren had these parts before the Geth attack.
 
A person with robotic parts will still have an organic brain, it doesn't make them evil (even in this fictional universe).
 

Are you prejudiced against other species or just crippled/implanted creatures? Shame on you...!

I really, really hope that the antagonist of ME2 is as imposing and badass as the Sovereign and Saren duo. Man, those two were the greatest villains EVER, especially Sovereign.

Yeah I rewatched that cutscene and you can definitely see the Geth left arm. I think since he only communicated in the form of giant hologram he was able to more or less hide his shit.

Most of the characters in the game have cybernetic parts.
