Is there poetic justice in "The Return of the Native"?

Whether or not there is poetic justice in Book Five is questionable. This book is Hardy's weakest in the entire novel. We might consider Eustacia's death a form of poetic justice, but only if she did in fact fall into the weir. Knowing she had previously considered suicide, an accidental death would be considered poetic justice, as she wasn't in control of taking her own life. It would have been taken from her.
