Having just completed my pure Renegade playthrough of ME 3...yeah, there were a few occasions that I basically had to grit my teeth and say "Gotta do it just to see how it plays out..."
<spoiler=I'm speaking, of course, of all the epic back-stabs that you pull off as ReneShep>1: Shooting Mordin in the back to prevent him from curing the Genophage. Mordin was always one of my favorite characters. Delightfully eccentric as salarians go, he was a valued member of my team in ME 2...hell, without him Shepard would have never been able to even fight the Collectors without the swarms freezing him and his squad for capture. And here you just straight up shoot him in the back...even I felt like a horrible person for doing that, but it had to be done for the sake of continuity in my Renegade playthrough.
Killing Mordin, in turn causes Wrex to jump you towards the end of the game, giving you the chance to gun his ass down as well. Things got tense on Virmire in ME 1, however I think that situation strengthens the bond of trust between Wrex and Shepard. Wrex remains a good and close friend through ME 2, however in ME 3 - going the Renegade route - he knows that you destroyed Maelon's genophage data back in ME 2 and is already starting to distrust you. Then you go and betray him and his entire race by shooting Mordin...and then you've gotta pump him full of lead on the Citadel when he confronts you about it.
But worst of all had to be betraying and killing Legion. Maybe it's because HK47 was my favorite character from the KotOR universe, but Legion quickly became one of my favorite characters in the Mass Effect universe. In ME 3, it makes it quite clear that the Quarians were being a bunch of dicks when they tried to wipe out the Geth. The Geth had absolutely no intention of turning openly hostile against the Quarians in the beginning. This paints them as the sympathetic race in that particular war. Annnnnnnd yet you refuse to acknowledge this, doom his race to death which prompts him to react accordingly: trying to kill you. This causes Tali to literally stab him in the back and sets you up to shoot him not once, not twice, but three frickin' times. I felt like I was putting down Ol' Yeller because after each shoot Legion looks back up to you as if wondering why it had to come to this...until you shoot his flashlight-eye out.
Yeah, all of the above situations made me feel like just an absolute horrible person. But hell, I had trouble picking to betray Samara and save Morinth in ME 2 because of how huge of a backstab that really is.
