Well, it's entirely possible the Elements could have been used to purify Stygian, but due to Star Swirl's whole "evil is evil" agenda and Twilight's insistence on going along with banishing him, we never found out. It's evident that the Elements can be used for multiple purposes, but it depends on the intent of their users. As for the Elements being sacrificed, I would presume that Star Swirl's spell would require something/somepony being sent to limbo with the Pony of Shadows. However, the darkness wasn't forced into limbo by the Elements, but drawn in after becoming separated from Stygian.
