911 Terrorist Attack

When I remember what happened on September 11, 2001 I don't ask my self  "why?!" because I know why mankind can be evil. I don't ask myself  "where was God?!" because I know he was with those lives but you have to remember God has given us free will and those terrorists made a decision that millions witnessed. Should we repay them with the same coin? Its one thing to make to make justice and have those who deserve it pay but another to enforce that same loss unto other cultures and religions for it. There is a difference between vengeance and peace. Peace is obviously not obtained with genteelness if mankind where gentile . Peace is discipline and discipline doesn't cause destruction but order.
