Only because she did not know what else to do. In an attempt to learn from her mistakes, Yangchen decided to be harder on her future self and demand that Aang deal with Ozai by any means necessary. Fire Lord Ozai was a man who would definitely take advantage of Aang and would drop the world into another 100 years of war and colonialism if Aang presented a peace treaty to the Fire Nation as a solution to genocide. This was something she was met with in her own lifetime but now on a greater scale. She saw that Avatar Aang faced an unethical man, Fire Lord Ozai, in his life time. Yee was able to create a history for Avatar Yangchen that would make an airbending Avatar reject her beliefs for the sake of the rest of the world, like she did in the TV series.
In my opinion, she only said so because she was now able to see, in death, the long term consequences of biased treaties and unethical humans based on the past F.C Yee created for her.Īs an author, F.C. In the Avatar the Last Airbender TV series, Avatar Yangchen told Aang on the back of the lion turtle that she would have done anything to maintain peace.
