Ye Wenjie experienced disasters and had a rough life. He witnessed his father's tragic death and was framed for many times. In the first half of the tragedy, Ye hated human beings, but she always believed that human beings could not save themselves and had to rely on forces other than human beings to save them. She contacted the three-body world and formed the Earth Three-body Organization (ETO) with Evans.
The reason of Ye's betrayal
After personally feeling the evil of human nature, I saw the evil of human nature in my works, thus thinking about the essence of human nature and thinking that human moral consciousness can only rely on forces other than people. The lack of dedication plunged her into a spiritual crisis and lost the meaning of life. In the loneliness of spiritual wandering, she got unprecedented opportunities, which is the only comfort for her repeated work for many years. And this opportunity can just practice the theory she has been thinking about for many years-transforming human beings, so she seized this opportunity and turned it into her own ideal, so she got the meaning of survival and could sacrifice all her dedication goals at any cost.
Therefore, no matter how arbitrary Ye's judgment of human values is, no matter how bizarre and naive she believes that high technology must have noble morality, no matter how arrogant she thinks that aliens can teach people on earth to be human instead of people who don't need to be "saved" to make choices. The choice was reasonable for her at the time. At that moment, that kind of environment was her inevitable choice.
