The novel vividly portrays the powerful emotions that lead Henry to forsake his idealism, reevaluate his understanding of bravery, see nature as an antagonistic force, and deny the presence of God. The violence he experiences lacks any redeeming aspects. By the end of the novel, the lessons Henry learns from war — the indifference of death, the futility of valor and patriotism, and the illusion of God — become so twisted and tangled in his mind that reality itself becomes blurred, turning everything into a falsehood. War offers no glory, not even for the heroes; it brings only death for the victims and confusion for those who survive.
