but does anyone know how it plays out at the goblin camp if most of the druids and tieflings are already dead?
At least in EA, there's no meaningful difference that I've spotted.
at least in EA, if you're intent on snatching the statue for Mol, I wait until I've resolved Kagha's shadow druids situation. After she's accepted the tiefs can stay, you can grab it and talk your way out of being suspected. if you wait until after you've offed the gobbos, you've lost your chance. If you're only grabbing as a snack for Gale, then any time after either of the above conditions is fine
