I think that's certainly an excellent way of looking at it. I doubt that Peter Jackson put that in, but we've already seen how dangerous it is to critique Peter Jackson for what themes he did or did not put in.
They spoke in the EE specials of how they had originally thought to put a scene in where Faramir had a slight vision of what Frodo could become, when he came to confront him in the back of their caves...a Gollum-esque Frodo. As well, Frodo saw the Shire in ruins in the Mirror of Galadriel scene. So I suppose they were somewhat conscious of the future that Frodo was striving to destroy -- both for himself, and for Middle-Earth.
