Voing for redcap, matches the title of the game, the "for the giggles" reason for the murders, the redcap need for blood, and if the hypothesis of the redcap puppeteering other people through a cult holds truth, the in-game tiny subplot of BOO-AAAAL.
besides, the "whiff of magic" and the thorns feels more feywild than goblin, and the redcaps are more closely associated with that part of Faerun.
