With all the Zeref worshipers up until now, it wouldn't surprise me if he was a Dragon worshiper. Or, remember how it was said that Acnologia was originally a human? But he used his Dragon Slayer Magic so much that it morphed him into a dragon? Maybe Future Rogue is on the brink of becoming a dragon, and he wants some other dragons to be his friends. And of course, no humans to slay him.
