I was rather hoping for a pointer to the Bible since you said it yourself that the first few times are OK but the 540th is probably not, after previously discussing the advantages of an eye for an eye. You weren't implying a figurative interpretation of the Bible then, as far as I could see.
Didn't Jesus also mention forgiveness when dying on that cross?
Oh, and by the way: When we had a discussion on Islam, many were quick to mention, and condemn, Sharia law. Why is the Old Testament's ideas about an eye for an eye OK when Sharia laws are not?
