Going After Cacciato, a Bildungsroman

Yes, I believe Going After Cacciato is a Bildungsroman, because Paul Berlin is on a journey to "find himself," to grow up, to come to terms with a reality he before was scared to death of. I hesitated to answer this way because in some ways, it doesn't seem like our main character changes that much; the book ends with him wetting his pants in fear of what he's had to do in the war. Yet, I have to say he has still grown and changed, and enough to call the book a bildungsroman. One instance that shows this change is when he is, at the end of the book, given the opportunity to leave by Oscar Murphy and he doesn't. Oscar challenges him, tells him he doesn't think he can or should do it, but Paul Berlin stays. Sure, he still wets his pants, but he stayed and fought, without escaping even by means of imagination.
