Yes. Almost every black belt I have known (and every single one of my teachers) always emphasized control, as in being able to control yourself. It was drilled into us that it was about responsibility, not bragging rights. Plus, if you are confident in your own ability to defend yourself, it’s a lot easier not to get scared and panicky.
I don’t think I ever saw a bully promoted to black (or even brown, for that matter); those behaviours were drilled out long before that.
