I think maybe you've just seen the movie, and been misled into thinking you know what Asimov's robot stories were about. I, Robot the book, has no bad consequences (likewise almost all of the other Robot novels...excepting the bit with the mind-reading robot and the 0th law leading to interesting results for planet earth...but it was still all for the good of mankind). The robots were all basically the good guys.
I'm not sure I understand how the existence of conflict has anything to do with my statement. You said, "how badly things can get out of control", and my recollection of the robot novels (and I, Robot, in particular) pretty much universally includes a few humans getting out of control and robots helping other humans put things right again. I don't see how your comment (either of them, actually) makes sense in that context.
