This thought didn't come to me before, but perhaps the reason Linlin wants to eliminate the Vinsmokes so suddenly is because Caesar Clown convinced her that it would keep her in control without the equalizing nature of diplomacy, if for no other reason than to save himself. Even if Judge doesn't have the knowledge and technology to turn people Giant, Caesar probably would've lasted even less once his talents and resources become Big Mom's to use. That's my theory, anyway.
