Blame it on them and blame it on them; for the Beastman at that time, all of this was no longer important. With the conditions they possessed at that moment, it was estimated that they could hope to annihilate the Human Race after a battle. And in that situation, regardless of who eliminated the Human Experts, none of it mattered to those Beastman anymore. As long as the Humans were destroyed afterwards, who would care about this matter now?
Or relying on the foundation of the Human Race, there originally was a possibility to resist the invasion of those Beastman. Yet, who let the Humans at that time display self-destruction themselves? After that incident occurred, the Humans dared to actively attack their Territory, and in that situation, those Beastman naturally wouldn't be polite with the Humans.
