Why is Cao Cao so suspicious?

Cao Cao is notoriously suspicious in history. Cao Cao was a famous figure in the Three Kingdoms period. Compared with Liu Bei, his family background is obviously much better, but he has a fatal shortcoming, that is, he is too suspicious and always feels that someone will harm him and want to kill him. It was his suspicion that led to the huge mistake of killing his father, sworn brother and family by mistake, and also made those who had been obsessed with fighting with him leave him.

As far as talents are concerned, Cao Cao attaches great importance to it, but he has a chilling feature, that is, I would rather die than die. Because of this sentence, I believe everyone should know how many people Cao Cao killed by mistake in history. It is precisely because of this feature that he lost the hearts of the people and could not get the love and support of ministers and people.

Of course, we know that Cao Cao's suspicion has certain roots, and he was assassinated by others several times in history. From then on, he almost didn't trust anyone and kept a suspicious heart for everyone. Few soldiers are willing to give advice and suggestions, and many consultants keep a respectful distance from others.

Cao Cao once asked many doctors to treat his headache, but it didn't work. I heard that Hua Tuo's medical skill was very good, so I asked Hua Tuo to treat him. Hua tuo just gave him an injection and immediately stopped his headache. Once again, Cao Cao has a headache. Huatuo's diagnosis requires craniotomy. Cao Cao flew into a rage and thought that people could not survive after craniotomy. He put Hua Tuo in prison and prepared to kill him. Let's think about why Cao Cao did this. Because Cao Cao was poisoned by the physician before. So he won't allow this to happen again.

We clearly know that Cao Cao's suspicion is not innate, but more determined by the environment at that time. Whether he betrayed Dong Zhuo himself or worried about the betrayal of others, his suspicion is not unreasonable.
