What is Gene's final assessment of Finny? What does it mean when he tells Finny he would not "suited" for war? Do you agree?

Gene finally realizes that Finny believed him to be "an extension of himself" (171). Gene never came close to extending the same kind of regard to Finny that Finny had to him; Gene finally has to realize how he failed his friend, and how his jealousies impeded a true friendship between them. Finny and Gene seem to be giving each other up here; it is one of the few times since Finny's return that the two have allowed themselves to be separated.
