I doubt they’ll dump the themes; it seems to me like they’re just backgrounding the specific labels. Heck, we’re starting in the middle of a Blood War battlefield, which is—coincidentally—probably the most prominent Law versus Chaos conflicts in the lore.
(Although in the Forgotten Realms, specifically, your afterlife is determined solely by your patron god and how well you served them. While some lore suggests that souls who didn’t worship a god are personally judged by the current god of the dead, most lore either strongly implies or outright states that they all end up as part of the Wall of the Faithless, there to slowly dissolve into nonexistence. It’s kind of messed up when you think about it.)
...from what I've seen they're quite reluctant to write genuinely 'good' characters, as if such people didn't exist.
