No, she was not a scheming and vicious person from the beginning, but because of the Chu-Han dispute, she became a prisoner of Xiang Yu, was tortured too badly, and often struggled on the edge of life and death, which led to her becoming a cruel and vicious person.

Historically, before Lv Zhi married Liu Bang, she was a very smart and beautiful woman, and she was kind-hearted. People nearby came to ask for marriage, which proved that she had a good personality. Moreover, after she married Liu Bang, she once went to the field with Liu Bang. An old man asked her for a bowl of water to drink, and she also gave it to her to eat. The old man is very grateful to her At the same time, she didn't insult Liu Fei who was not her own, which shows that Lv Zhi is a kind-hearted and hardworking person. It can only be said that nature played a trick on people, which led to her later becoming cruel and vicious.

The key to her complete change was the four-year Chu-Han War, because Liu Bang's influence was not strong and could not compare with Xiang Yu's. Lv Zhi was captured by Xiang Yu, often tortured and insulted by Xiang Yu, and basically struggled on the line of life and death. One thing that makes Lv Zhi even more chilling is that before the war, Xiang Yu once fought with Lv Zhi's two armies.

I wanted to kill Lv Zhi to threaten Liu Bang, but I didn't expect Liu Bang to say with a smile: Kill if you want, it has nothing to do with me. Although both sides are braver than anyone else, from Lv Zhi's point of view, it is estimated that they are cold from head to toe. What kind of friendship do you have for Liu Bang? This can be seen from what she did to Liu Bang from behind.

To sum up, it was because Lv Zhi took Xiang Yu as a prisoner that she completely changed. In the future, everything should be done first, and the root cause should be eradicated, just to protect ourselves from danger.
