I really doubt that they will use the Biblical serpent but you never know. I would say it is some kind of weapon much like the one he tried to use in the satelite. As for Eden maybe he means if the Light does not accomplish their goal then he will activate the " serpent" destroy all mankind, then start out with just two people rebuild the world and making it into a perfect society.
