I have most of his books Apart from some of the later ones about football and trains etc. This has indeed become an interesting discussion. I have a problem with cutefying DnD creatures though.. Where does it end? Aww poor mindflayers, just doing what they do poor wee things.... :O No!!!!!!! They are monsters!!!! Kill them with fire!!!!! And so on.
It doesn't have to be about cutifying them, just provide more context for why certain races are the way they are. Think about goblins specifically, their society is based entirely on survival. They have to be sneaky and cunning to not get eaten or smashed by everyone else. In comparison with the average humanoid nation goblins are at a massive disadvantage, hence why they'll group up with other monsters or evil leaning sorts for protection.
The goblins in BG3 aren't mindless killers, at several points in the game they have the opportunity to attack you but go for threats first instead, they will fight if they have to but generally seem to want to avoid it if they can.
They aren't good, but I would hesitate to call them totally evil either. I mean, Wyll for example tries to be pretty charming, but when the goblins come up he goes full on genocide mode. xD Truly man is the real monster. x)
