Hey Bug, sory you have to see your son hurt like that. Definitely one of the hardest parts of being a parent.
Completely get letting them work their own R out. Doesn't mean support can't be given though. Validation of how son is hurt and taking an opportunity to offering guidance if it happens is ok too IMHO. But your S has to be open to it of course.
If he is like your H, then he may be acting in a way he feels he should by what he has seen. How can he see something more healthy so he can learn a better way?
