Túrin feels that, by changing his name, he can alter his fate—that if he is not Túrin, son of Húrin, Morgoth’s curse might not be able to find him. This, as Gwindor knows, is not the case. Túrin’s fate is his to accept or struggle against, no matter what name he takes. By changing his name so frequently, he forgets to instead alter the behaviors and tendencies that lead him to misfortune. Túrin’s belief in the power of his new names is arrogance, as is his refusal to listen to Gwindor’s advice.
