I voted 'kill everything!' I can see that Larian would not want to do this though, since someone would latch onto it and it would be blown out of all proportion (I am not sure what rating the game has?). A pity, since having unkillable NPCs is very inconsistent.
It has an 18 (Mature) rating in the UK. Not sure about other countries. One of the many things I love about RPG's, they tend to be aimed at mature gamers which means for the most part, fewer of the "family friendly" nerfing/sanitizing pressures are present.
It's Mature in the US. Frankly, MANY families in the US wouldn't be phased by the killing of tiefling children. Parents let their kids watch Return of the King at very young ages with decapitated heads and eyeballs popping out. BG3 is tame compared to some of the stuff parents here are letting their kids watch these days. I was a kids' pastor for years. I heard all about what parents let their kids do. Call of Duty, Battlefield, etc... They're more of a norm here for kids even as young as 6 or 7. It's sad, but true.
So, my point is, it wouldn't be a big deal in terms of censorship if they allowed tiefling kids deaths. Again, do I want to kill them? Nope. Even when I played my evil Drow sorcerer, I was glad the goblins did the job for me. Do I think tiefling kids should be able to die? Yeah. No character should be invincible unless they're like Withers and have a GOOD reason to be invincible.
