What are the personality characteristics of the important figures in The Romance of the Three Kingdoms?

Luo Guanzhong's Cao Cao is a typical treacherous, cruel, willful and suspicious villain.

Chen Shou believed that Cao Cao was the "No.1 in the Ming Dynasty" in the history of the Three Kingdoms, and that "the magic of application and transaction, the unique strategies of North Korea and Belarus, and the materials given and received by the government were all their own devices, and they were hypocritical and arbitrary, and they did not think about old evils." Cao Cao has been in charge of the army for more than 30 years, but he can't let go. He must be endowed when he climbs high. He is better at poetry, cursive script and Go.
