Yes I think the shame and guilt discussion is probably relevant here. Although Japan has a shame culture, and the West supposedly has a guilt-based one, I'm not convinced that guilt is all that widespread anymore.
I think that specific subquestion is an interesting one for sure (whether guilt has been replaced by strong authority, like it's not wrong unless you're caught and punished).
I'd love to see how it trends with factors like responsiveness in the political system (Canada vs the USA vs Russia or whatever), wealth inequality and social mobility (both between and within classes), softer things like expectations of "honor", etc.
