After Eddie got back from the war his leg was still hurt and he was hurt mentally from the war. He didn't get out of the house much. One day his dad got very angry and started yelling at him to get up and get a job. He ended up throwing a punch at Eddie and that was the last time they talked.
When Eddie and the other soldiers were captured they were treated very poorly. They didn’t get much food and were sleeping on uncomfortable beds. This is man vs society because it was Eddie against the enemies that held them captive.
When Eddie found out that the captain shot his leg on purpose his reaction was terrible. He got immediately angry and started to punch the captain.
