Caranthir
"But Caranthir, who loved not the sons of Finarfin, and was the harshest of the brothers and the most quick to anger, cried aloud: 'Yea more! Let not the sons of Finarfin run hither and thither with their tales to this Dark Elf in his caves! Who made them our spokesmen to deal with him?'" The Silmarillion, Of the Return of the Noldor
