Do u think Leper's assessment of the Army was correct? ANd is so, could he be deemed insane?

Leper becomes a symbol for what the war does to young men like himself, especially since he has a breakdown before he even gets overseas. Leper's tale is supposed to stand for what happens to innocence when it is suddenly overwhelmed by experience or reality, and Leper is chosen to be the object of this lesson because of how untouched and peaceable he was before he left. War can do great damage to the human psyche. I don't thenk Leeper can be declared insane. His flight from war, to many, seems more sane than staying.
