O'Brien changes..

In "On The Rainy River" Tim O'Brien was contemplating whether he should go to war,both the author and the character. The author did not actually go to Canada he spent this time playing golf(which would definetely not be interesting to read about) O'Brien was frightened and was not sure what decision He should make. His whole frightened and soft side faded in "The Ghost Soldiers". He describes to the readers the pain that came with being shot. Where He used to be concerned in doing the right thing O'Brien changed. Maybe it was the cruelty of war that made him lose sight of doing the right thing. He felt this great need to get revenge on a fellow soldier. He was mistreated by Jorgenson and that could have led to the evil that came out of him.
