I haven't played an FPS for a long time, except for Spec Ops to see what all the hype was about, and I definitely felt the disconnect about all the killing there. But for me, personally, I've almost always had this kind of feeling to some degree in games where we are killing people who aren't necessarily villains. I can't think of any specific FPS examples, though I remember vaguely playing games where I've just been expected to gun down the innocent police force/other 'good guys' or even morally-grey characters simply because they're the next obstacle to what my character wants to do, despite myself being able to see the less murderous alternatives.
As I play RTSs a lot more often, an example that immediately jumped out at me when I read this article was Warcraft 3, when Arthas starts killing everyone in his way on the way to the evil sword. I know he was basically possessed at the time, but his allies just went along with it with only a few grumbled complaints. I think some ended up leaving, but they would still go along with all the killing up until then.
It's kinda common in RTS story modes that I get to a point where I'm thinking, "The justification for me killing all my own faction in this mission is kinda flimsy and probably didn't need to involve all this violence to resolve."
