As that proxy above said, stop trying to understand every image. They're poetic, they're meant to be felt. But anyway, let me give you an explanation for that one as well: the whole film is a fable. I grasped that image in the sense that for others to live some need to die, it's the eternal cycle of our world. Although I'm not sure that whale even died, after the credits at the end of the film there is a scene where I think I spotted him.
