With regard to the story of the Gadarene demoniac & the herd of swine, Andy is correct that the demons prefer the pigs to deportation. However, he is not correct that the demons wanted to destroy the herd. They didn't. They just wanted a place to hang out, since their human host was no longer an option. The pigs, however, were unable to bear the demonic presence, and went mad, running blindly over the cliff to their deaths. Where the legion of demons went next isn't told in the story, but we we all have our ideas about that.
