They have their own system of government and can choose what reasons to fight this group or another. Orcs on the other hand don't govern themselves and listen to Sauron and his allies.

Since all Orcs/Goblins are perversions of Elves by Morgoth for the sole purpose of doing his bidding in mockery of Elves, I don't see how Orcs/Goblins would have come to NOT listen to their master, as we have no evidence throughout any of the works that this would have occured
