Why is Jonas bothered by the game of war Asher and the others play and why can't he make them understand that they shouldn't play it?

Jonas is bothered by the game of war because it trivializes the concept of violence and death, which he has come to understand as serious and painful through his experiences in the community. He feels that the game reflects a lack of empathy and awareness among his peers. Despite his attempts to convey the seriousness of war and its consequences, Jonas struggles to make them understand because their upbringing has conditioned them to see it as just a game, devoid of real meaning or consequences. This disconnect highlights the limitations of their societal values and Jonas's growing awareness of deeper moral issues.
