1. Liu, the sixth emperor of Liu and Song Dynasties, mentioned the notorious tyrannical emperors of Liu and Song Dynasties, and he was bound to be inseparable from Liu Mi. In 464 AD, Liu Jun, Emperor Xiaowu of Song Dynasty, died, and Liu ascended the throne naturally. Since Liu took office, he has shown a series of abnormal behaviors. The first manifestation of his tyrannical nature was the wanton killing of officials, especially after killing Dai Faxing, and his tactics were even more unscrupulous. Later, he even killed his own uncle. In addition, Liu also has a very abnormal hobby. In private, he likes to order maids to have fun without clothes, and there are even rumors that Liu is incestuous.
2. Before Liu Mi, the king of eastern Hunan, reached the summit, most people had high hopes. At that time, Liu was tyrannical and his ministers were anxious, and the life of the people in Liu and Song Dynasties was in dire straits. However, after reaching the summit with high hopes, it proved to the world that his tyrannical degree was not inferior to that of his nephew Liu. Liu Mi may have suffered a lot that year, and his mind was distorted, so his mentality was extremely complicated. He likes to doubt the people around him. He killed his own blood relatives, but showed no mercy to those who were kind to him. In addition, Liu Mi has a unique personal hobby, and likes to watch nude performances.
To sum up, I don't think a tyrant in the traditional sense can be like Emperor Liu Song. It is no longer simple cruelty, but personality defect and psychological distortion. Therefore, I think this level of brutality is probably hereditary psychosis.
