IBO is super interesting. "The establishment is the establishment and most of the time it wins," is the final outcome, but the road there is actually rather fraught for that establishment, and it's alternately almost damned and just barely saved by aspects of its rule and operations. The winning agent of the establishment wins, in part, because he skillfully threads through the requirements of his station while strategically breaking taboo (but only once he's certain to have the political backing to do so). On the other side, the rebels are

>driven by the circumstances the establishment has forced them to contend with for the entirety of their short lives (they're all child soldiers, btw)

>are only able to find their successful path by rejecting establishment and forging what seem, at the time, to be canny ties with other groups on-the-margins

>...right until they follow that path off a cliff.

The "heroes" and "villains" remain who they are at the end not just because of affinity bias (having spent more time with the rebels than the establishment), but because there's a tangible disconnect between the former feeling forced into the poor decisions that they make, and the latter's rather cold, and unforced, determinations.

So when Shino almost takes Rustal's bridge out, I am, of course, cheering, even while I know I'm watching him commit a war crime and sign his own death warrant. When Rustal orders atmosphere-braised pilot skewers, it still feels incredibly unfair, even when I know why he made that decision. They threaded the needle.
