The anime is the only version of the story where one student deliberately murders another. Nobody in the novel is killed by their classmate; quite a few are killed by one's grandmother, though. So it's not necessarily about age. The Calamity is kind of like the Flood; young, old, sympathetic or not, everyone is equally killable.
