I really can't see Yang engaging in a course that she knows would upset Ruby. There's a big difference between mischievious teasing and this sort of unpleasantness. As I say, I think that it would be Weiss ("I can pay people to ruin your life") and Blake ("Accidents happen") who are most likely to be aggressive.

Yang would be more likely to tease Jaune too and then act like a blonde-haired boxing yenta (matchmaker). She'd only lash out if Jaune had done something to upset Ruby, no earlier.
