Why didn't Emperor Wu of the Han Dynasty rehabilitate Wei Zifu after discovering the truth of the "witch curse"?

Wei Zifu did participate in the rebellion, which is a fact, so there is no way to rehabilitate him. After Wei Zifu became queen, the Wei family's power began to grow rapidly, which made others dissatisfied. So a group of people began to plan how to make Wei Zifu fall, and witchcraft became the best way. In the process, the prince resisted and finally committed suicide because of fear. Wei Zifu saw that his sons were all dead, and what he was doing also committed suicide. Emperor Wu of the Han Dynasty saw that his son and wife were dead, and he also reacted. It seems that it was framed, so he investigated it thoroughly. The result was indeed framed, so Emperor Wu of the Han Dynasty rehabilitated Liu Ping.

But in this process, Wei Zifu is not a pure Bai Lianhua. First, she used the Queen's power to release Liu Yi, and then opened the armory to let her son take up arms to resist. This is also a normal idea. Do you want her to watch Liu Yi get killed? Therefore, Liu Yi did rebel, but he was forced to do so. Emperor Wu of the Han Dynasty knew about it, but he didn't think it was wrong. After all, rabbits have to bite when they are anxious.

But it's wrong to put it on Wei Zifu. A queen actually released the prince privately and gave him a weapon. This is simply deliberate rebellion. A woman should stay in the palace and take part in some things. Moreover, as the mother of a country, she should help her husband win the rebels and thieves, instead of helping her son fight against Laozi, which made Emperor Wu very unhappy. And the emperor also thought, if anything happens to him in the future, will Wei Zifu also open the armory and let his son be emperor directly? At this thought, the emperor felt that Wei Zifu was not a simple woman.

Emperor Wu of the Han Dynasty was also an emperor who attached great importance to emotion and righteousness. Although the Wei family committed a crime, they were rarely involved. In his later years, he also built a four-story platform to commemorate his son.
