It is a culture that is familiar with the adage of "if the punishment befits the crime".
I heard a remark not long ago from a female acquaintance who, when asked what she would do if she ever caught her boyfriend cheating on her, she said... well, you probably know the answer she offered. The thing that striked me though was another person's retort to her comment, something like: "You sound so asian... I, mean, with the whole penis-chopping remark..."
Where as in some cultures if you get caught cheating, it is the three lashes and the barracks, or perhaps a flogging and a chastity belt, but it would seem as though in the East, there is little room for mercy when it comes to 'poor little john'.
