"If you know [that the Universe will be destroyed by a Tralfamadorian pilot who presses a button]," said Billy, "isn't there some way you can prevent it? Can't you keep the pilot from pressing the button?" "He has always pressed it, and he always will. We always let him and we always will let him. The moment is structured that way."Â
Vonnegut, Slaughterhouse-Five.
