Catch-22 Chunk #4

During this chapter Yossarian becomes more of a perve and as nurse Duckett is fixing his bed he decides to put his hand up her skirt and as she runs away Dunbar grabs her behind. Once a Doctor finally rescues her, he confronts Yossarian and he uses his sanity as an excuse. The doctor decides to send him to Major Sanderson, the hospital psychiatrist. Dobbs comes and visits Yossarian at the hospital and again tells him that he is willing to kill Colonial Cathcart. After Yossarian admits that he thinks someone is trying to kill him and that he is not comfortable with the war, Major Sanderson really believes he is crazy and suggest that he be sent home. But as happy as Yossarian may have been there so happened to be a identity mix up and another patient was sent home instead of him. He goes to Doc Daneeka but Doc refuses to ground him for his insanity, he felt like if all the crazy soldiers went home then who would fight in the world.

Yossarian decides to see Dobbs to tell him to go ahead and kill Colonial Cathcart. But, Dobbs had already finished his 60 missions and was awaiting his arrival home, so he no longer had a reason to kill him. So he suggest that he have Orr help him kill Colonial Cathcart, but Orr had crashed his plane while Yossarian was in the hospital. While in their tent Orr suggest that Yossarian fly with him some day just in case he will one day have to make a emergency landing. After arguing over if women like Yossarian, Orr flies another mission and crashes in the ocean again. But, this time is different Orr disappears.

Question: Yossarian has had multiple chances to get away from combat and even came close to being able to go home. Do you feel that the author is foreshadowing something to come by not allowing the character to be able to leave ??
