How to evaluate the sentence "leading people across the river, hypocrite, killing real heroes"?

The hypocrite who led the people across the river said that Liu Bei and the butcher killed Cao. This sentence is a bit wise after the event, thinking that Liu Bei was too kind and did not forget to run with the Jiangnan people when he fled. As a result, Cao Cao was caught off guard and became the laughing stock of the Three Kingdoms. On the other hand, Cao Cao was ruthless and slaughtered Pengcheng, Yecheng and Liucheng. For Xuzhou people, he committed heinous crimes and slaughtered three or four times. Hundreds of thousands of men and women become bones, and Surabaya does not flow. In Cao Cao's famous sentence, the bones are exposed in the wild, and there is no cock crow in a thousand miles. He wrote about his own slaughter of Xuzhou people.

In the end, although Liu Bei won Jingzhou and Yizhou and dominated the southwest, Cao Cao unified the richest Central Plains generation in the north and was also the most powerful in the Three Kingdoms period. Cao Cao and Liu Bei are both politicians. It's really unreliable to describe them as hypocrites. Their personality characteristics are extremely complicated.

It is true that Liu Bei has never slaughtered ordinary people in his life, and he embodies the image of benevolence and righteousness everywhere, but he is unforgivable to political enemies and celebrities who don't keep their mouths shut The most immoral thing Liu Bei did in his life was to connive at his subordinates and plunder the property of the people after he captured Chengdu. But we must know that the Three Kingdoms period is a bloody era. People's lives are not as good as dogs. A handful of grain can sell for more than 500 thousand, and people eat people everywhere.

Liu Bei asked his men to rob more property, which was nothing to the people compared with giving them a stable and peaceful living environment. Although Liu Bei loves to run and cry all his life, he embodies benevolence and morality everywhere, but he is not a hypocrite. Even if people now cross back to the Three Kingdoms, most of them are willing to follow Liu Bei instead of the bloody Cao Cao. Liu Bei's escape and crying are also true colors. The biggest performance of Cao Cao's hypocrite is to hold the emperor to make the princes, and historical figures are always complicated.
