Not annoying at all. I'm more annoyed by people just letting me keep making the same mistake without saying anything. In fact when I first wrote that something in my brain said maybe it wasn't right, so I looked up the word "scruples" and saw the definition "motivation deriving logically from ethical or moral principles that govern a person's thoughts and actions." I thought maybe that it might be a valid interpretation for the ethical or moral principles to be flawed in that context. What I should have done was look up examples of "lack of scruples" being used in sentences; that would have made it clear that I wasn't using it right.
