I have to disagree with you on the matter of Grimoire Heart. They were kinda like Magneto. They wanted a world of infinite possibilities for strong mages, while thinking that anyone too weak to survive there wasn't worth the effort of protecting. They didn't try to kill everyone just for fun or for the sake of killing.

Hm... Silver relation theories... Even though it lacks even the slightest hint it'd be quite ironic if he turned out to be related to Mirajane. Father: Demon Slayer, Daugther: "The Demon" ^^

Unlikely as hell I know.
