Catch 22 was perceived as making people crazy due to war. Yossarian went crazy and thought he was going die many times. In Catch 22 there was no perspective of the Jews. Yossarian asked to doctors many times to admit him into the hospital so he wouldn’t have to go on missions. He tried to convince Dr. Daneeka that he was going insane.
In the Hiding Place the war made the Jews strong. The formed a Dutch resistance group and fought until they died. They thought fight until we die. They never stopped no matter what. Hans told Attie before going into the orphanage to find Ruta and he said that we fight until we die. He knew that there was a high probability that he was going to die but he was brave and went to go save Ruta.
The second difference is where the movies happened. Catch 22 happened on a military base and there were no big shootings or bombings. There was one bombing that took place but that was done by their general. People were never scared of being executed.
In the Hiding Place there was a house called the Hiding Place where Corrie ten Boom hosted several Jews. They were several times the Nazis raided houses and raided theirs too.
