After some help I've chosen this blog:
It is often said that a soldier can come back in two ways: in a body bag or a changed man forever. Being a war veteran himself Kurt Vonnegut want to show how war affected him and other veterans, showing how a war is not worth life lost nor the lives changed. Kurt Vonnegut uses the idea of time travel frequently throughout the novel. As the Tralfamadorians would advise "Billy to concentrate on the happy moments of his life, and to ignore the unhappy ones-to stare only at the pretty things as eternity failed to go by" (194) what we must recognize is that Billy had no free will, choosing where to travel to. He may have well be in the Trafamadorian zoo and go right to his childhood. Particularly striking is that with his time traveling he can also see the future. Billy knows exactly what his fate holds for him and yet he does nothing to alter it. Seeing this I want to answer a question frequently asked: Is Billy Pilgrim Crazy? Yes, without a doubt Billy is crazy Kurt Vonnegut not only does he shows us this thought the novel with Billy's actions, but he uses time traveling to prove how war drives people crazy, in this case Billy. As we are reading Slaughter' House-Five we are thinking, "all this happened, more or less" (1). What I'm seeing now at the end of the book is what Kurt Vonnegut real message behind the book, behind all these aliens, and time traveling is what happens to soldiers after they have lived through a war: they become mad.
