I don't think it would really matter if Rou was human or not to the Codex Great Hero was rather vehement about how dangerous of an existence the World Enemy is. It doesn't seem like he'd waver no matter what race he was. He even advocated sending all their forces along with the Beast Kingdom and Magic Kingdom's at the start, believing that Rou would be that much of a threat to everyone (everyone agreed, mostly because the treasures received from defeating Rou would help to make up for their losses and that they'd also leave behind 5 of their heroes to defend their kingdom while everybody else is away). The Holy King left it up to the 4 Cardinals to decide whether or not they should engage in a fight with Rou, and was up for whatever course of action they'd decide to pursue.

As for their human supremacy principle; they don't really intend to kill off all monster races, as they believe that would be against the 5 Great Gods' will (since they were also created by them). It's just that they believe monster races should be treated below humans. All in all, they were rather level headed when they made their decision. The author definitely didn't portray them as being villainous at all (although, the Savior seemed rather obsessed with fighting and killing Rou, which seemed to unnerve the Holy King; can't blame her, I guess, as she was constantly in a state of dying until she received her job), so the author might be writing them as "noble elitists". They're definitely going to lose, but I don't think they're being set up for a big fall.

Going with the "Wisdom King" theme Rou has and that the book from which the Codex Great Hero read about the World Enemies from was called "Trial of The Gods", they might end up being forced to change their stance towards demihumans and monster races by the end of the war?
