I really don't think Larian is trying to actively teach any moral lessons with the game. They have their own perspectives that are appearing in the story, but that happens with every story. But I do find it baffling why they turned that druid immortality thing into a ritual when it's meant to be just an automatic thing that happens. However in defense of Karlach not asking for the ritual to be done to her, the way it works is that druids are ageless, but they can still be killed. So it wouldn't fix the engine. And doesn't Jaheira say that it's a thing for old druids anyway? I've only seen the scene once so I don't remember it very well.
Pretty sure 'evil is supposed to be evil and unrewarding' line from the interview begs to differ pretty hard. Offering perspectives is 'what is evil or good,' eg game assumes x character in the story is justified in their actions or not but the player might disagree personally. BG3 takes it further in punish/reward the
player in gameplay for being 'right' or 'wrong' and often pre-supposes
why an option was chosen instead of letting the player define it. It's what puts far more linear RPGs like Witcher 3 over it in terms of choice and consequence for me, because BG3 and the writers of it come across as very preachy.
