"What doesn't kill you makes you stronger". Do you agree with this statement? Why or why not?"...Fingon cut off his hand above the wrist, and Thorondor bore them back to Mithrim. There Maedhros in time was healed; for the fire of life was hot within him, and his strength was of the ancient world, such as those posessed who were nurtured in Valinor. His body recovered from his torment and became hale, but the shadow of his pain was in his heart; and he lived to wield his sword with his left hand more deadly than his right had been." - The Silmarillion - JRR TolkienSo many of these questions make me think of Thangorodrim. And well they might, for it was the event that forged me to be what I was ever after, and still am.
I do not know how long I was captive in Angband. Some say I hung on that mountain for fifty years, which is frankly ridiculous, not even the strongest elf could have lasted so long in such conditions. I lost count of the time I was held captive in the dungeons below the mountain, but I would be surprised if it were longer than three or four years. As for hanging on the cliffs of Thangorodrim, that was only when Morgoth grew bored with me, and was but a few days. I was almost dead already, even at the start of that final torment, and would likely have lived not many more days had Findekano not found me.
Did it make me stronger? People said that it did, but I'm not convinced. It certainly made me
harder - a tough shell, a thick scar that covers and protects the tender flesh beneath. My body healed though the scars remained, and my right shoulder never quite fully recovered, always to give me pain again in cold weather. But inside, I never did heal. Always there were nightmares of the torture, and that shadow on my fea that changed me for ever.
I do not think that the experience made me stronger because it did not kill me. I think it only failed to kill me because I was already as strong as I could be. Had I been any weaker, I would not have survived.
I am made of copper, forged in the fires of Angband.
