Sorry for the late reply. Yes and no, because the debate on whether Good and Evil are cosmic or karmic forces changes from game to game.
Goblins, kobolds, faeries, pixies and brownies are actually just exchangable descriptions for the average D&D commoner to describe "tiny ugly humanoids" that robbed us, killed some of our livestock and are generally ugly to be around. When described that a group of goblins has raided a nearby farm, make sure to get a proper description, else your group might be caught in a weird game of fey origin as said goblins are suddenly brownies and other fey instead of the expected low level mooks.
Remember, the farmer has half a dozen hearty children, a wife and a toolshed full of make-shift weapons. He could fend of something as poorly coordinated as a goblin raid. Fey however? Their grandma has told them not to screw with fey.
