Nearly all Koreans in the entire nation are "shamed" and have lost "national face".
This is something clearly culturally impossible in our US society, steeped in individualism, where just about every man and woman, in a sense, is an island, disconnected from the larger.
Most of the news I’ve read said the shooter had been in America since 1992. If he was 23, that would have made him eight at the time his family left South Korea. I guess his family, both here and there, are really shamed by this if his native country is.
