Liu Bang successively abolished Zangcha, Zhang Ao, Han Wangxin, Peng Yue, Han Xin and Ying Bu. When Liu Bang proclaimed himself emperor after the founding of the People's Republic of China, he became more and more suspicious of the heroes who fought the world together in his later years, especially those kings with different surnames.

Not only that, he had doubts about Xiao He. This forced him to try to tarnish his reputation to dispel the emperor's suspicion, and finally he almost died a natural death. Before he died, he planned to kill the loyal Fan Kuai, because he was the husband of Lu, and he was worried that he would help Lu to make a mess. Only after Chen Ping's protection and Liu Bang's death did he escape.

The reason why Liu Bang didn't kill Sean:

Sean made great contributions to the establishment of the Han Dynasty. The most well-known achievement is to fight with others at the Hongmen Banquet, unblock the struggle between Xiang Bo and his father, and help Liu Bang, the Emperor Gaozu, get away with it. We all know what happened afterwards. Sean won the trust of Liu Bang at the Hongmen banquet.

Kill all the loyal subjects, but not Sean. To find out the reason, we must first analyze Sean's personality and attitude towards life. Although Sean is a talented person, he is definitely not a person who loves money and luxury. At first, he followed Liu Bang into this world, not for wealth, but to release his talents.

Therefore, people say that Sean is not actually working for Liu Bang. He doesn't have a high salary, but he works for himself. It can also be said that he is working hard for his ambition, and this ambition is definitely not power. Just because Sean's idea of not taking power was seen through by Liu Bang, Liu Bang thought that he was no threat to his dynasty.
