You most likely killed someone accidently then because if you don't kill anyone he says that he appreciate the restraint you have shown. When I went mix of lethal and non lethal in 2nd playthrough I heard 2 guys in office talking about how Jensen is a loose canon. If you get seen during the mission to retrieve evidence you get told that there have been reports of an aug breaking into the place, if you take then out then in conversation with Smiley Jensen said something like they were in the way and I took care of it to which Smiley reacts with distress. If you didn't then Jensen says "They didn't even know I was there" and Smiley says something like you see what happens when you listen to me?Opening scene's gotta be the worst writing I've encountered in this game so far. Dubai and that were both baffling in execution. The train bombing's tackiness wouldn't be so bad if the game didn't remind me every few hours that it was suppose to have been an emotionally significant moment that affected Adam in any significant way.
There are about a billion ways they could have written that and the subsequent related scenes better. Instead they tried to have it serve as both a snippet of how bad tensions are, an emotional grounding for Adam in the story, and a Metroid-like moment where you lose all of your abilities. Then it fails to commit to either of the former two enough to make it matter.
I haven't encountered any so far. I went through the Rucker mission without killing anyone. When I get to Rucker, he told me not to kill any more of his men. I haven't encountered anybody around the office commenting on Adam's performance in missions either.
