The Deep Logic of Dark Forest: Why Was Luo Ji the Only Swordholder?

The Dark Forest Law is the most core sociocosmological principle in the Three-Body Problem series. Many people only remember the eight words 'Hide yourself well, do the cleaning well,' but ignore the profound game theory foundation behind it. After Ye Wenjie revealed to Luo Ji the two axioms and two key concepts of cosmic sociology, it took Luo Ji decades to truly comprehend them. Why is Luo Ji the only qualified Swordholder? I think there are several points: 1. Luo Ji truly understood the dark nature of the universe without any illusions. 2. He mastered the essence of 'deterrence game' — making the other side believe you dare to perish together. 3. His feelings toward humanity were a mix of responsibility and disappointment, which ironically created the most stable deterrence state. In contrast, Cheng Xin gave up deterrence at the critical moment because she couldn't bear the moral weight of destroying two civilizations. This confirms the cruelty of the Dark Forest Law — the universe is not a fairy tale. What do you all think the Trisolarans would have done if Wade had become the Swordholder?
