Precisely why I used that comparison. Bruce's act of breaking someone's nose, in a fight while attempting to subdue someone, is excessive violence. It's extreme, over-the-top, painful and disfiguring and dangerous, more than is needed and more violent and cruel than can actually be justified.
It is in every way more extreme than a superficial cut to the cheek.
It is far more brutal compared to what is actually required to subdue someone, than a cut to the cheek is compared to what is actually required to keep someone subdued.
