I think that a lot of us DO see Tony are far more pragmatic than some of his other heroes (eg, Steve). He doesn't have to like it, but the end does justify the means sometimes -- his actions in Civil War show that. But saying things about his "morals" seems to change the meaning -- morally flexible makes it sound more like Punisher or Deadpool. Fraction might mean just want you said, it's just that the way he phrased it puts Tony in a negative light when I read it. :/
