"Hehe, what do you think?" Robin laughed, pointing to the map, "Even if you all stayed inside the headquarters for months trying to come up with a master battle plan it wouldn't necessarily be any better than this."

In fact, Robin wasn't angry when he heard that Sakaar decided to extend control over the central, southern, and western regions. On the contrary, he was happy, and almost punished Charles, but Charles then continued and told him that he intended to take over the eastern region as well, which made him hesitate a little and stay silent.

When Robin left Nihari, the remaining Demon Emperors were less than 300. If he had given them the task of protecting the central region, it would have been a fantasy, and perhaps it would have even led to some kind of internal rebellion.
