Some of the non-syndie Norwegian branches are fine, as are some of the paths for the other Scandinavian countries and Finland. Depending on how the game plays out, some of the Central American branches are fine--SocDem Nicaragua->Centroamerica or liberal any of them -> Central American Confederation -> RadSocs (who promote racial equality and neutrality in this configuration, unlike in Centroamerica!). RadSoc Indochina also seems pretty moral in general, especially if you push for women's rights, although it can get up to some questionable things with land reform and has some expansionist paths (of course, it doesn't have to take them). Gandhi's Bhartiya Commune is an obvious candidate, too, especially if everything gets in place for the peaceful union with Delhi. I'd also put in a good word for monarchist Hawai'i--looking at the focus trees, they restore the rights of the native Hawaiians, establish a constitutional system, and set up various forms of welfare--although from what I recall the king option was a wife-beater and the female option a playgirl, so that might take them down some notches.
Other than that...syndie Australasia, especially if it remains neutral? A democratic Russia that devolves power to the communes seems fairly moral (certainly it's pretty much as moral as you can get with Russia, the total opposite of Savinkov), same with a peacefully formed Soviet Union that picks, IIRC, the autonomists--the ones that really do want to give the minorities plenty of power to do their own thing--although both are expansionistic enough that it might be a problem. Some of the South American countries can remain pretty democratic and free, without getting into any wars. So can Costa Rica, Panama, and Cuba, obviously depending on how you play. I'd put democratic or socialist Iran on here, but they have a strong expansionist bent. All things considered Haile Selassie can be relatively moral--integrating Eritrea, reforming society to establish a constitutional monarchy--or, of course, not. Honestly, it's kind of hard to figure which countries are the most moral. Aside from a few exceptions that have only "evil" or "bad" paths--Mongolia, Romania, Mittelafrika by virtue of being a colonial enterprise--most have paths that are at least somewhat good, or about as good as could be expected.
You also missed Fonte's Argentina on your list of "bad" regimes, although that might be covered in your "minor Totalist". I think it probably should be bumped up a notch, though, if you're putting natpop Argentina on there. I mean, it's literally a bandit kingdom, so it seems quite on par with the Mad Baron...
