The MBI leader is completely crazy, that much is clear, so being a badguy isn't really an issue to him. And apparently he was a lunatic well before this all started. Like his assistant tried to say: The line between a genius and a madman is very thin indeed.

I'm still hoping Minato would get a grasp and start to plan something. He's not as bad as his sister but he's still acting like a happy-go-lucky dolt considering the place always was a battlefield and now it's one also officially.
