About Garrus' kill list, I didn't think any of them were cruel. Most of the deaths sounded like they could have been almost instant. "Suit malfunctions" are deaths that can happen in-game with Overload and Sabotage. Killed by a stolen weapon could be as easy as Shepard picking up ammo in ME2, except with Garrus grabbing one of the stolen weapons when he runs out of bullets. The red sand overdose, I think, would have been done by shooting a crate filled with the stuff, which Shepard can do too - I imagine he screamed for a few seconds in pain and then died, much quicker than the krogan Shepard can kill with the Renegade interrupt. The only one that confused me was the cough, but I agree with Nilfalasiel's theory about that one - the guy might have been interrogated when he had suit damage from battle (or if not in battle, we all know Garrus can be rough in his interrogations, even if a suit break wasn't his original intention), and one of Garrus' men could have been sick. They had to live in some pretty harsh conditions, probably with no medical supplies other than the basics and medi-gel for injuries, and if quarians can be allergic to non-dextros, a virus from a human/batarian/krogan could be fatal. I think he died during the course of the interrogation.
I also doubt that Garrus really wanted to harvest Saleon's organs. It sounded like a threat to me, similar to Shepard's "shortest interrogation ever" dialogue. Sometimes people just say things like that to scare the other guy. I know none of my Shepards would really do what they said to Kelham. Beating him up, and not making the death quick? Sure, but like he said, they didn't have the time. Paragon Shepard would probably disapprove, but a lot of Renegade Shepards wouldn't, so I don't think he was holding back because of Shepard. They were on a more important mission, and Garrus didn't want to take too much time away from that - at least, that sounds logical, and it's a very turian way of thinking.

First off, I agree with Kim about Saren. We had a very nice Saren analysis fest here a few weeks back where we broke the guy down. I'm sure I could dig it up if you want to see the nitty gritty of some of our Saren interpretations. We had another one about indoctrination that also explains a lot with Saren.
Sarenfest was fun. xD Longest wall of text posts I ever wrote here on the forums. Is it linked in the archives yet?
