[Morsul the Dark]

yes but when have you heard of an orc quoting history

the goblin king in fact knows the history behind bilbo's sword(so do his followers)

Orcs only ask about how good sport hobbits give

Orcs in my opinion resemble neanderthals they have a chief and live in packs while goblins are more feudal with a king and im willing to bet a better knack at inventing(they live in caves...deep in caves)one can assume theyre excellent trap makers for food while orcs chase down their food(although wherew all the food comes from is still a mystery

also one last thing Saruman's uruks can ride wargs as can goblins but ive never heard of orcs riding them. one can only assume the uruks knowledge of this craft came from their goblin predecessors
