See, when I saw this thread topic, I thought we were gonna be talking about slavery. You know, the thing that confirmably exists in multiple nations we've visited (I've counted at least four, more if you count 'Garlemald' and 'Garlemald-occupied nations' separately).

Something we have to remember is that the game setting is not 21st century Earth, and does not share its morality. It's very nebulous exactly what level of comparative development the game world is in, since over the course of the game we see nations based on things ranging from 19th century Japan, Crusades-era Vatican City, to a 17th century mythical city, to a mashup of the Roman Empire, Nazi Germany and Cold War Eastern Europe. But all that can really be confirmed is that FFXIV's world hasn't caught up to us. That's just fine for a story, but it does mean that they haven't gotten to modern cultural mores like 'completely outlawing outright slave trading' and 'completely understanding that torture is bad'.

They're getting there, though. Limsa is several centuries ahead of the curve in recognition of the sins of colonialism.
