I like the concept and symbolism of the devil - as the opposition in all things to the concept and symbolism of the Savior.
I can accept a literal or figurative Lucifer - but I don't like many of the extrapolations that have grown up around the devil. Having said that, the Mormon take on Lucifer (one of us gone really, really bad) is the only one I've studied that I like.
