"Don't judge a hero by his success or failure" comes from "Zhuangzi * Pirates of the Foot".

In the society of the Spring and Autumn Period (actually not limited to the Spring and Autumn Period), small thieves were arrested, while big thieves who stole the country became princes. Duke Huan of Qi Xiaobai killed his brother before becoming the king of Qi. After becoming the king, he took his sister-in-law as his own. For such a person, the famous sage Guan Zhong was willing to assist him. Tian Chang, the minister of Qi State, killed the King of Qi, stole the State of Qi, and became the King of Qi himself. For such a great thief, the sage Confucius accepted the money Tian Chang gave him without any shame. If discussed, this kind of thing is really not worth mentioning, but even the sages have no objection to them. In fact, what’s so strange about this? "Shangshu" says: "Which is evil and which is beautiful? Those who succeed are the first, and those who fail are the tail."

This was also the case in later societies. Su Shi of the Northern Song Dynasty said in "Preface to the Praise of Kong Beihai": "The world judges people by success or failure, so (Cao) Cao is among the heroes." Unfortunately, such loud voices from Zhuangzi and Su Shi are not often heard. An opposite idiom is "Don't judge a hero by his success or failure." Those who make this appeal are mostly on the losing side. The Kuomintang was defeated and fled to Taiwan. Taiwanese newspapers often use the phrase "don't judge a hero by his success or failure" when talking about it.

Thank you, give me points
