I have no idea what the future has in store for Saji, but whatever it is, he wasn't wrong. The CB was an ally of the Throne when the summary execution of the party people happened, and while they later clashed with the Throne, it wasn't them that took the Throne out of the sky and punished them. In fact, right now the CB saved the very Throne pilot who slaughtered all of Louise's relatives. What is going to happen next to Nena pretty much defines the moral standing the CB is going to adopt in the future.

If Nena is set free or even allowed to join the CB, it means the CB is ultimately the same as the Throne (anything can and will be sacrificed for the "peace", arbitrarily), or if they punish her by themselves or make sure she's punished by others (unlikely as she might have information they don't want the world powers to get) they would have the kind of higher moral standing Setsuna is always dreaming of.

Well, I guess more strictly speaking Setsuna could now let Nena go, this one time, to pay her back saving his own skin during the mass operation back then.
