In "The Canterville Ghost" by Oscar Wilde, what does the ghost's honorable burial tell us about basic human traits?

In Chapter Seven of the story, the Canterville ghost is buried in a "wonderfully impressive" ceremony at Canterville Chase. This about-turn in the treatment of the Canterville ghost illustrates an important point about human nature: that people are prepared to forgive any sin, so long as there is atonement. We see this most clearly in Chapter Five when the Canterville ghost admits to all manner of sins, including the murder of his wife, to Virginia Otis. Despite her disgust towards his many atrocities, Virginia realises that the ghost genuinely seeks forgiveness and thus agrees to help him to enter the Garden of Death. This is not only evidence of her kind and generous nature but also of Wilde's message that no sin is too great to be forgiven. Furthermore, it is this idea of forgiveness which brings about the story's climax when the Canterville and Otis families are reconciled at the ghost's grandiose funeral.
