Which character in the Three Kingdoms who killed the benefactor at the expense of interests is now regarded as a hero?

Speaking of the Three Kingdoms, people can often think of many wonderful stories and many flesh-and-blood characters. There are Guan Yu of Guan Yunchang, who is called a warrior, and Zhu Gekongming, who is called Wolong. There is another role. Although he is notorious in history, it is his usual practice to forget righteousness for profit, but what he brings to people in his novels is a heroic image. Being praised by later generations as Lu Bu among the people, he served Lu Bu first. Speaking of Lu Bu, people often think that a Chinese Odyssey is a good man, good-looking and affectionate.

However, in real history, Lu Bu is a cynical person. Lu Bu was an ordinary general in the late Eastern Han Dynasty. Although martial arts is very high, there is no background in troubled times. After the death of Emperor Ling of Han Dynasty, Lu Bu was appreciated by Ding Yuan for his martial arts. Lyu3 bu4 also appreciated Ding Yuan's kindness and satisfied him, so he worshipped Ding Yuan as his adoptive father.

As a result, Dong Zhuo led the army to Beijing, and Ding Yuanchao disappeared. As an adopted son, Lu Bu did not become an adoptive father in Out of the Mud, but defected to worship Dong Zhuo as an adoptive father, personally killed Ding Yuan and made a gift himself. Then, he was lured by Wang Yun's honey trap and had a contradiction with Dong Zhuo. In order to satisfy his own desires, he killed Dong Zhuo, who had given himself an official title.

The ancients paid great attention to loyalty, but Lu Bu sold the Lord for glory many times, which naturally made people look down on him. However, in the novel, Lu Bu is described as the best military commander in the world. Although Lu Bu changed hands many times, it played down Lu Bu's subjective feelings and made readers feel that what Lu Bu did was helpless. Killing Dong Zhuo for the story of Dixin is also portrayed as a love story in which Lu Bu values affection and righteousness more than Dixin's story. Who doesn't like the image of such a martial arts odyssey, who has the honor and right, and who wants to be angry with beautiful women? Ironically, everyone knows the story of Lu Bu and Di Xin, but they don't know that Di Xin's story is just Lu Bu's concubine. So, I don't know if Lu Bu is a hero, but the villain didn't run away.
