You're still missing the point. Any person in Ted's shoes would've taken their own lives to escape from AM's torture, but instead,he seizes the one opportunity he has to escape from his hellish life to free the people he was with, showing that even after 109 years of torture he still has genuine human emotions. What you did here was take a tragic ending out of a horrifying story and applied it to a bland, under developed, movie in an attempt to make it more profound, doing the exact opposite in the process. Lastly, a dark fic only works if it is believable. As said on TvTropes "When badly done (especially when the original work was a comedy), it will do nothing but squickreaders, who will quickly abandon it. Or make people laugh. Well done, though, it can provide an intense and unsettling view of something supposedly familiar." Your story was the former of the two.
