There are some descriptions of heroes killing innocent people in Water Margin. For example, Song Wu killed the supervisor's family after the blood spilled on the Yuanyang upstairs, and Li Kui jy killed the onlookers after robbing the giving ceremony.
1 most of these rebellious heroes portrayed in the novel have experienced too much human suffering and torture, and become numb and cold, bloodthirsty and indiscriminate.
Deep down, they also sympathize with the weak, hope to help the poor and are eager to communicate sincerely with others, but they are repeatedly deceived and ridiculed by real life, making them more and more inclined to split personality.
