I still think the Commandment is sound.
For me, the fact that the story seems to have what
you would call exceptions makes the events all the more real to me. Infact, if it was all fake then it would be seemingly perfect to an unbeliever, yet to an unbeliever it is not perfect. You see, if it was fake then surely you would alter the story, it seems to agree well with the reality of life.
You are talking about the Commandment to the Jews and putting an event under that Commandment. However, G-d has also said , again when you take the full bible into consideration, that he that even gets angry with his brother is in danger of the Commandment. So, for you to say that there are exceptions to the rule is for me a half-truth. Yes, if a kiddy is getting hurt like Sidelined suggested, I could see the sense in that. BUT, saying G-d makes exceptions because of an event in the OT is not solely acceptable because Christ said things like:
" In the past it was an eye for an eye a tooth for a tooth, but now I say turn the other cheek " -(similar words)
He also says he who is without sin can cast the first stone. Infact, he makes it impossible to justify violence, have you considered the full teaching Paul?
