it would be a Utopian mindset if we could all live together in peace and harmony, helping our fellow man, but you show me a period in history where there wasn't conflict and wrongdoing. And where there is this, there will always be retribution. It is in the human nature to defend against whatever they may feel to be wrong, whether their own personal views are "right" or "wrong".
And where you have this, you will eventually have some form of war, on a small, (neighbourly), or large, (any present conflict) scale. You won't stop it, BAS, and neither will I.
