Once he recovers from his undirected rage, Beah concludes that if Gasemu had not delayed them, he would have seen his family. He attacks Gasemu, eventually striking him with a pestle. The other boys hold Beah back again; Beah’s anger infects them and they turn on one another, some blaming Gasemu for their not rejoining their parents, while others defend Gasemu as innocent of any intentional harm. Gasemu intervenes to stop the fighting, insisiting that “None of this is anyone’s fault.”
I don't find this reaction at all unusual. Can you imagine being so close to your family, only to lose them when your on the other side of the hill?
