What is Justice?

With what little I understand or can perceive as particularly “Chinese” about both Thunderstorm and Snow in Midsummer is the idea of justice manifesting in a balance being struck, and one’s actions coming back to effect life later. I may be completely off base with this but I think this particular content of the play is Chinese or at least Asian in its perspective.
In Snow in Midsummer Dou E is able to bring the balance of justice to the world through her righteous living and her “cursing,” so to speak, the world to prove her innocence. Conversely, Chou remains alive and that life has been irrevocably affected by the uncovering of his past injustice. He may mourn the assumed death of Lu Ma decades earlier and even try to fulfill a type of ancestral filial respect, but he harmed her in the most egregious way. Nothing short of the sacrifice of all his children can atone for this. Even losing his own life seems to not be enough to make amends.
This is one aspect of Thunderstorm that I found particularly fascinating. The adults who committed the transgressions (Lu, Fan, and Ma) were not killed, thus leaving the future generations to suffer from the elders’ sins. Instead the progeny of “sinners” (so to speak) are wiped away and the older generation is left with the tatters of a former way of life. I’m not certain at all if this is “Chinese” or just the playwright’s viewpoint on his world. Ma’s heart wrenching monologue wherein she laments that her “poor children, they didn’t know what they were doing” and “The guilt is here in my heart, and I should be the one to suffer for it” seems to tell the audience why the children are killed in the context of the play itself. Again, is this the playwright's worldview or cultural perspective?
Nonetheless, she certainly gets her wish. The parents will finish the remainder of their lives with the burden of so many destroyed lives. It seems to me to be a Western concept to end the story with the deaths of the older generation and the younger having to clean up the inherited mess. But, I’m not sure which play or movie planted this idea in my mind. Perhaps my conceiving that type of ending is a product of Western, “the sins of the father will be visited upon the son,” Judeo-Christian culture.
