Mastering the inner game of bullying/harrassment

In grade school while in class, children would sometimes shoot paper darts with a rubber band at someone sitting in front of them. Often the class would end and all would be forgotten. However, if the harassment went on for a long time, the child in front would get so irritated, and they would snap and do something violent to whoever was harassing them. Of course, the teacher would only see/hear the violent reaction and would get no backstory about what led up to it. And the victim would end up looking like the bad person. From my perspective, in addition to being angry at the person harassing them, the victim is also frustrated at themselves for losing control after being provoked. What does Buddhism have to say about this? A victim might intellectually try to resolve their problem by saying that all is "maya", but their anger would still be real. There is still an "I" that is being harassed. When fists can't resolve the problem, what other approaches can one use?
