Because Sima Yi later became cruel and heartless because he was really exposed, and became a butcher. There are also different opinions on Sima Yi in history, because Sima Yi is indeed a very talented person, and his talent can be compared with Zhuge Liang. However, in his later years, Sima Yi was very cruel, so he was blamed a lot.

Sima Yi was not so cruel when he was young. The original Sima Yi was just a counselor. Although there are some treacherous means, he is not so bloody. Therefore, Sima Yi, a soldier who surrendered voluntarily, is definitely not a killer. Therefore, Sima Yi had a good reputation when he was young, and he was also an outstanding figure with great wisdom.

Sima Yi, 59, started the road of butcher. It stands to reason that Sima Yi, who is almost sixty years old, should look down on everything, but Sima Yi seems to be regressing. At this age, he already has the blood of young people. Therefore, after Sima Yi broke into Xiangcheng, he began to slaughter the city. Not only that, he also pushed the bodies on both sides of the road to show off. Such a cruel battlefield makes people afraid to look straight. Many people think that Sima Yi should not be like this as a general, but Sima Yi did it.

In the battle of Gaopingling, Sima Yi even spared the woman who married outside. Sima Yi not only mistreated soldiers at ordinary times, but also took control of the Cao Wei regime in the change of Gao Pingling. Therefore, Sima Yi, once the core figure of Cao Wei camp, was spared. I wonder if I killed the red-eyed Sima Yi. Finally, even married women were killed. Sima yi was seventy years old that year, and in this way, in his later years, he left the name of butcher.
