It is possible to suppose that Hardy added the sixth book only to make things come out right for her; at least, his readers seemed to have demanded it.
Her only fault, from her aunt’s point of view, is that she persists in wanting to marry Wildeve even after she has not been well treated. But from the reader’s point of view, this is a fault only in the sense that she is too generous in her attitude toward others, too willing to do the right thing as she understands it. So, in the novel, the innocent suffer too, though not irreparably.
