Reason 1: water under the bridge. Even if Emperor Wu of the Han Dynasty realized that his witchcraft had killed the Prince and his wife, it was impossible for the two relatives to be resurrected. It is true that he showed regret in his later period. He committed a crime and built a platform for thinking. His power is greater than the sky, but the dead child will never appear again in this life, which is irreparable. Moreover, after the former prince committed suicide, Emperor Wu of the Han Dynasty re-established Fuling, Liu Yuxin, and the decision has been issued, and the imperial edict has been issued. Nothing in particular cannot be changed. Things have reached this level, there is no need to dwell too much on the past.
Reason 2: In the Han Dynasty, Jiangshan and Dynasty, it was a very serious matter to remain neutral to the vassals. If it is not handled well, it will easily lead to partisan strife, and the result of infighting is likely to be beneficial to foreigners. Emperor Wu of the Han Dynasty was a very hard worker in history. He knows how important this matter is and how to weigh the pros and cons. So in this case, he chose? No preferential treatment? Liu Bingyi can make the world in the Han Dynasty more stable. Hereditary system developed to the Han dynasty, which has been very stable. The old prince was abolished, and the throne had little to do with Liu Mai. So even if Liu Bei? Recover? The emperor's throne has nothing to do with Liu Bingyi. But there are always many coincidences in history. If Liu Fuling didn't die early, the next emperor wouldn't be Liu Bingyi. Being good to him will only bury hidden dangers for the stability of the dynasty.
Reason 3: the emperor's mistake Even if the emperor is wrong, he will not show that he is wrong in a big way. If you are kind to Liu Bingyi, he will explain to the world that he is a bad king who listens to gossip. It is one thing to build a platform for thinking, but whether you want others to say that you have done something wrong is another matter. It's like someone is willing to laugh at themselves, but they will be angry when they hear others say that they are not good. How could the emperor be wrong? The emperor was right when he was wrong.
Reason 4: If you can't be kind, what is kindness? Pass the Crown Prince to Liu Bingyi? This is obviously impossible! What if? Kind? Liu Bingyi gave him the status of a prince, so Liu Fuling, the prince at that time, would think so. What would other princes think? This is a problem that has no solution and cannot be balanced. What's the best way? Not friendly? Liu Bingyi, so that everyone can live in peace.
In the end, the emperor is different from ordinary people. When he makes a decision, he has to consider many things and balance the relationship between different places, so it is sometimes difficult. Liu Bingyi's life is really ups and downs, so he has become the protagonist of many plays, and there are also many anecdotes.
