So, I've been back reading the thread after catching up on the quest, and there's been a lot of interesting discussion on the morality of the Bronze Faction and the Realm. Something that I've really come to appreciate after reading through some of the setting books is that that discussion is relevant in-character essentially only for Sidereals.
No matter how good an argument you have for why it should be done, the Lunars and Solars are hardly going to allow themselves to be slaughtered en masse, and while you can probably find quite a few Dragonblooded who would go against the Realm, it would be ridiculous for them to therefore say that they should hand over the mandate of creation to the Solars. Leave aside the morality of the issue, there's just no reason that the vast majority of Dragonblooded would give up their own rule even when they disapprove of the specific current rulers. It's only the Sidereals who are trying to keep Creation stable and ask "okay, whose leadership would be better for Creation?" No other Exalt group would plausibly go against their faction en masse.
And obviously even within these factions different Exalts conduct themselves with different levels of morality, but the base question of "Who should rule over Creation?" isn't answered initially on the basis of morality, it's either "these guys want to kill me" or "being the elite class of an empire benefits me," and then later they decide how to conduct themselves. So at the end of the day, the nicer Dynasts who don't abuse mortals are roughly on the same side as the guys with the monopoly on the slave trade (we can see that right this very update) while being closer to them than even the most careful and least bloody Silver Pact member, and the same is true for that Silver Pact member with the Lunar who runs around opening Shadowlands in Realm satrapies.
I think this all this leads to a very dynamic and enjoyable setting, since everyone is mostly acting for their own benefit, and when they don't, it's for interesting personal reasons. There's no set "good" faction, it's possible to look at the setting from any given faction's side and cast everything in a new light.
