Yossarian's attitude toward his roommates turned merciful and protective at the mere recollection of Captain Black. It was not their fault that they were young and cheerful, he reminded himself as he carried the swinging beam of his flashlight back through the darkness. He wished that he could be young and cheerful, too. And it wasn't their fault that they were courageous, confident and carefree. He would just have to be patient with them until one or two were killed and the rest wounded, and then they would all turn out okay.
Yossarian reflects on his feelings toward his roommates, recognizing that their youthful cheerfulness is not their fault. He acknowledges his own yearning for that same youthful spirit but feels burdened by the grim reality surrounding them. As he walks through the darkness with his flashlight, he wishes for a sense of joy that he feels is slipping away. He grapples with mixed emotions about their innocence amidst the chaos of war.
Despite his protective instincts, Yossarian accepts the harsh lesson that may come as a result of their courage and carefree nature. He thinks that, in due time, tragedy will strike, forcing his roommates to confront the brutal truths of their situation. This acceptance showcases his complex view of human resilience, where he hopes that through suffering, they might emerge stronger and more aware of their circumstances.
