Starline doesn't actually like Eggman.
He likes this idea which he created inside his own head about what he thinks Eggman should be. But he doesn't understand Eggman. He can't comprehend really basic stuff like the fact that Eggman will literally never respect him as an ally. Or that he doesn't "share", as Eggman himself put it.
Whatever it is that Starline likes, it's not really ... connected to who Ivo Robotnik is as a person.
