Ordinary men in Yossarian's base are dying and no one is able to change that. The idea in the minds of the troops was the belief that the ongoing war was based on unnecessary reasons. There were reasons such as colonels wanting to fight for promotion and so on. Some of these troops are reluctantly risking their lives and dying because of the Catch-22 rule that the bureaucracy has set for the troops. First, during the war, many soldiers die, including Yossarian's friends. Their deaths are unnecessary and it is even harder for the other troops because they know this war is not necessary. “Behind him, men were dying. Spread out for miles, the other planes [shot down and falling over the target in the same way]” (Heller 136). In the book, death is described as a humiliating experience and soldiers are killed and deprived of their human dignity. Then, many soldiers on base were more afraid of dying on a mission than of dying sick in the hospital. “People knew a lot more about death in the hospital and did a much more careful and orderly job. People gave up their souls with delicacy and taste inside the hospital. There was none of that crude and ugly ostentation about death which was common outside the hospital” (Heller 165-166). Soldiers were prepared to die in hospitals rather than on missions. Indeed, death in hospital allowed them to die with dignity, without exploding in the air or burning on the ground in their planes. Finally, a soldier from the Yossarian base was shot down while in his plane and no body was found. His parents were visiting him but he wasn't there so Yossarian had to pretend to be him and pretend to be dying. “Of course you’re dying. We are all dying. Where the hell do you think you're going? » (Heller 182). The doctor makes Yossarian understand that no matter the day, he will die and that death is imminent..
