I've said it before and i'll say it again.
Goblins are peak ubermensch.
They're like a bunch of little Conan the Barbarians. They're too small to raise livestock, because them getting charged by a goat would be like us getting rammed by a rhino, so they're civilisationally stunted a little. So they have to hunt to survive. And what do they hunt?
Humans, elves, half-orcs, tieflings, Dragonborn...
Imagine being a caveman, having to hunt Mammoths to survive, and now imagine those mammoths stood upright, wore armour, carried weapons and was at least as intelligent as you. And also, some of them had scales, or massive horns, or moved as quick as the wind, or they could pop you like a fucking grape with a muscle twitch.
Goblins hunt monsters just to survive, and their society in-game should treat that like it's fucking glorious, because it is
the only reason we feel bitter about it, is because we're the monsters.
