My experience is that ONLY countries that 'benefit' from the fear / shame / guilt of christianity (even if people latterly turn to atheism) have such introspection. I must modify that - it's not all correct - I think that when people have also been brought up with essentially a Greek philosophy background and a faith in empirical testing and analysis. ah - lets combine the two; then you get this desire to correct and improve - and the culture to do so.
