You could argue that everything the humans have done so far has been to survive when given such destructive power that years of discipline and training (or, if you like, brainwashing) is necessary. Their entire civilization is geared toward making sure one of them doesn’t abuse their powers; a single one of them can wreak havoc if they want to. This includes killing children that have abilities they can’t handle, hardly a godlike way of handling things (well, depends on the god, and what chapter of the holy book you’re reading), yet the queerats call them that, well, some of them still might.
So these future, godlike humans have raised an imperfect race of rat-creatures that have learned, or have been taught, the human ways of civilization. We get the Robber Fly colony freeing themselves from slavery to a queen, which sounds like a good thing, but now the queen is kept like a beast in a stable, a reproducing machine. They didn’t have to do that. They could still maintain their “free” society (rather more like a dictatorship with Yakomaru at the top) while treating the queen with dignity and respect. This more savage route they took instead tells us that the humans who bred and guided them thought them as no more than serfs in the first place and gave them no instruction on philosophy or even basic respect for fellow human beings, who approve and watch their bloody battles with an almost sporting interest. Now the Robber Fly colony has grown in sophistication and turned on the humans. It’s what everyone should have expected when human beings act as gods. Interesting that Satarou says the attack was the colony’s last=ditch attempt to save them from annihilation; I have no doubt that given more time the Robber Flies would have attacked the humans anyway.
And because I’m human, I guess, I found myself nodding my head when Tomiko admitted hate for Yakomaru and what he had done. But on the other hand, we have Saki, who might feel that way too, but she’s more interested in finding Maria now that there’s no doubt she’s still alive (so did Tomiko lie to the council about the bones?). A human being trying to reach out to a friend, even though the friend is most likely responsible for the Robber Fly colony’s success. Maria and perhaps Mamarou have become as savage as the society that wanted to kill them for good reasons are. Saki is about the only one left who has any sort of, er, humanity about her.
Some weirdness, too. Like that one soldier who died and whose soul appears to be a woman. And Shisei’s double pupils. Just enough to make us blink while the heavy stuff goes on. There’s so much the show is doing now that I don’t see any way they can wrap things up this season.
