Cao Cao was authoritarian but did not dare to kill the king, why was the Sima family arrogant and wa

Because there are not so many people who support Cao Cao, if Cao Cao kills the king, then he will be a sinner through the ages.

Because Cao Cao at that time was the same whether he killed the monarch or not, he already controlled the power, but Sima Yi was different, and killing the monarch could let him live.

Cao Cao had his own plans, not afraid, to coerce the Son of Heaven to make the princes better, but Sima did not plan to do so, so he dared to kill the king.

Killing the monarch no longer has any meaning for Cao Cao, he has already controlled the power, but Sima Yi is different, killing the monarch is his only way to live.

Cao Cao didn't dare, but there was no need, and it was better to coerce the Son of Heaven and order the princes. The Sima family is just more direct and not so hypocritical.

Because Cao Cao called on the world in the name of the prime minister of the Han Dynasty, he did not dare to kill the king, but the Sima family was different, he called himself the Duke of Jin, and he had the idea of changing the dynasty.

Everyone's personality and methods are different, and Sima Yi is too ruthless because he is afraid of death.

It may be that people at that time thought that this matter was very serious, but the Sima family did not think so.

Maybe it's because everyone's personality is different, and Cao Cao and Sima's thoughts are also different.

Sima Yi's usurpation of power was not a personal act of the Sima family. As an influential local tyrant, Sima Yi has been co-opting and colluding with other gentry. Sima Yi's usurpation of power was supported by these gentry.

It is because Cao Wei's economic system does not conform to the interests of the upper and lower classes, and it is inevitable that the wall will fall down in the end.

Sima Yi is a big traitor with a thick face and a black heart, but he also has insight into human nature, and he is especially good at disguising himself.

Because they didn't have the strength to oppose it, Sima Yi, the old fox, used the method of boiling frogs in warm water to wipe out almost all their power.

Because the situation did not allow it, at that time, Wei was in the outside world, and without the Sima family, it could not resist the army of Shu.
