Why do most ancient people put righteousness over life, and sacrifice their lives for righteousness?

Because in ancient times righteousness is very important, no together is equivalent to live in the world, no spirit of survival, it is better to die meaningfully.

But there is righteousness, is not a good end, such as the "Water Margin" in the Liangshan Po of the good man seems to be a group of peace and harmony, all the good man between the liver and gall bladder, full of righteousness of the atmosphere. In fact, the Liangshan good men are not so nice, the fight and killing heart between them, are always there. Song Jiang was able to take the first place in Liangshan Mountain, it was the wise star Wu Yu and Song Jiang who planned to take it from Chao Gai, and make Chao Gai's head.

Song Jiang also suppressed Chao's faction during the ranking of the many great men of Liangshan, and those who followed and supported Song Jiang were named the Big Dipper, while those who had followed Chao were categorized into the Earth's Fury. On the issue of the imperial edict, the good men of Liangshan also had different opinions, which finally made the good men die and disperse, and from then on there was no more flag in the world to act for heaven.

Whoever reads "Water Margin" knows that Li Kui is one of the most righteous people on Liangshan Mountain, and he can turn his face against Song Jiang for the sake of the people, and he even wants to kill Song Jiang. Li Kui in Water Margin is not only a murderer, but also a good man of loyalty and filial piety. He can do justice to the people as an errand boy in the county office, which can show that Li Kui is very kind-hearted. When Li Kui impersonated Li Kui, he knew that Li Kui wanted to fulfill his filial piety, he did not kill Li Kui, but released him. It is a good example of Li Kui's respect for people with filial piety.

But in the final recruitment, Li Kui became a nail in the eyes of Song Jiang, and only Li Kui's death could preserve the name of loyalty and righteousness of Liangshan. Li Kui finally died in the hands of the most admired and most die-hard followers of Song Jiang.
