Yep, people are the damndest conflagaration of scruples to be defined.
If there are more of use who enforce peace than those who wish violence, we will have peace.
History, I am afraid proves me wrong. The few who create death, war, violence are almost always neutralized by the same methods they choose to unbalance the peace.
Not the best way to view maintaining harmony or peace, but that is the lesson of our history to maintain balance, and harmony.
People choose to screw it up.
