Mainlanders firmly believe in collectivism; whereas, western audiences in individuality.
Therefore, Chinese people believe it is okay to kill a person to save the group. Whereas, other countries do not.
Mainlanders think that is being selfish.
The idea of prioritizing collective good means that it's ok to sacrifice one (or more) people if even more people will benefit from that action by a certain threshold amount.
This... isn't that. Arresting this guy won't help or save a bunch of people. The government just wants revenge for his financial crimes, and they're unethically using his kids to try to get it.
Collectivism is commonly seen as a valuable presentation in conformism-driven social environments.
