"Moral lessons" from a game that offers every possible form of coitus can hardly evoke anything but black irony.
That’s the freedom you actually get from the game.
You can choose to take a path that leads to a moral lesson about monogamous love winning over the worst of violent upbringings, or you can take a path that leads to "moral lessons" of sacrificing your parents for experiencing the bliss of forgetting and sex after desecrating a holy place with the blood of a heavenly being.
It’s a path you choose, and the moral lesson follows your decisions. And I love that: the game does not tell me what’s right. It has a starting situation that you can shape and it brings consequences — though with some tweaks so most choices lead to a strong outcome (not necessarily a moral one).
If you got a moral lesson you disagree with, that’s the result of your own choices — seen through the eyes of a writer in Gent, Belgium, who takes them up to create an interesting narrative with character development. If I interpret the careers page of Larian correctly, that’s where the writing team sits.
There’s one limit to this, though: if you make a deal with the devil (regardless of whether that’s serving Vlaakith, becoming a mindflayer, joining the absolute, accepting the power of Baal, or signing a literal deal with a half-devil) then there are consequences that block paths to morality. Those choices are similar to the hard choices in Dragon Commander, though much softer.
And I love that. But maybe that’s because I personally like black irony, so you may have hit that spot on …
