Monica, I respectfully disagree with your pessimistic post.  Violence is, like most things, a learned behavior.  The majority of adults never commit an act of serious violence in their lives.  Creation myths, including the Judeo-Christian, try to explain the inexplicable, but they are simple starting points.  In our tradition, after the Resurrection, Christ says, "Peace be with you."

As for Newtonian Law,  it concerns inanimate objects.  People are a lot more complicated.  Also, the seemingly definitive Newtonian Law has been surpassed by much more difficult findings of 20th century physics.
