1, killed his first adoptive father Ding Yuan for a little profit.
This happened when Dong Zhuo was conquered. At that time, Ding Yuan had a son, Lu Bu, who was so powerful that no one could beat him. So Dong Zhuo was always beaten back and forth. At that time, someone told Dong Zhuo that Lu Bu was a man who loved money very much, and he could be bought as long as he was given a little benefit. So Dong Zhuo took out a lot of gold and silver jewelry and a red rabbit horse and sneaked into the barracks at night. After seeing the benefits, Lu Bu killed Ding Yuan, the adoptive father, and gave Dong Zhuo Ding Yuan's head. It is conceivable that such a person, how can he get the love of others?
2. Killed his second adoptive father Dong Zhuo for a woman.
When Lu Bu was bought by Dong Zhuo, he made a lot of exploits under Dong Zhuo, so Dong Zhuo also accepted him as his adopted son. At that time, Dong Zhuo ran amok in the palace, and the old minister of the Han Dynasty couldn't bear it anymore, so he made mischief, using the story of a geisha who lost her heart to make mischief between Dong Zhuo and Lu Bu. Lu Bu is a person who has no feelings at all. He personally stabbed Dong Zhuo to death for losing Sim's story. In this way, Lu Bu killed his adoptive father again.
Seize his city from those who take him in.
At that time, Lu Bu was defeated by Cao Cao. In desperation, he asked Liu Bei to take him in. Liu Bei relented and took him in. However, Lu Bu took advantage of Liu Bei's sending troops to fight, and Zhang Fei stayed in the city. When he got drunk at night, he took the opportunity to take the city. This is the third time that Lu Bu has been unkind.
To sum up, Lu Bu's character is terrible. Zhang Fei once called him? Slave's third surname? It shows that he has three fathers, which shows how bad his character is, so although he is strong in force, he is unpopular.
