Song Wu killed Pan Jinlian and Ximen Qing, which is a capital crime. Why did he only get a stab at Meng Zhou?

In Water Margin, Song Wu is the hero who fights tigers, and yanggu county infantry is the leading figure. The county magistrate saw that Song Wu was skilled in martial arts and handsome in appearance. Pan Jinlian, a prostitute who wanted to be promoted, poisoned her brother Wu Dalang. Song Wu was heartbroken when he came back. He suspected it was his sister-in-law, but Pan Jinlian said it was Wu Dalang.

He died of heartburn, but Song Wu didn't believe him, and Pan Jinlian refused to plead guilty. Song Wu sued him in the county government. Because there was no evidence, the magistrate of a county closed the case in advance.

Song Wu found the coroner and knew the truth about his brother's death. He called all his neighbors together and killed Pan Jinlian on the spot.

After the second time, Ximen Qing was killed. After killing Ximen Qing, he turned himself in. The magistrate asked touts to write documents lightly. Song Wu was stabbed in Mengzhou, and Wang Po was killed in this year.

In ancient China, there was a saying that "it's only natural to kill people for their lives", which meant that killing innocent people should pay for their lives, and killing guilty people should not pay for their lives. Song Wu killed Ximen Qing and Pan Jinlian without asking, but was sentenced to stabbing Mengzhou to death. Besides, he is a hero who fights tigers. His brother was killed for revenge, but he did it a little hard. He killed Pan Jinlian and Ximen Qing, and made his neighbors testify and turn themselves in. So there is no death penalty. In ancient China, the death penalty was generally executed after autumn, because everything died in autumn. In ancient China, people thought that human activities should be consistent with the changes of nature, and the spring and summer when everything grew were not suitable for execution, so the death penalty must be executed in autumn. Unless the judgment is executed immediately, it must be approved by the emperor.

Song Wu's murder, according to the present statement, belongs to revenge afterwards, the circumstances are particularly bad and the social harm is particularly great. However, in the ancient judicial environment of China, the death penalty could not be sentenced. Because Ximen Qing and Pan Jinlian are both guilty people, this kind of person who is guilty of murder is allowed to reduce his sentence in the ancient judicial practice of China, otherwise he would not be sentenced to death at all.
