The people who commit violence against people in this country, do not appreciate the liberty available in this country nor should be resident in it. Any person that wakes up in morning with the intention of killing anyone, is an idiot. Its simple : never pick up a gun, join an army or beleive in another persons ideology, trust your own morality. The problem with this belief, isn’t that life is more complicated than it, but that some primitive people still see violence as a shortcut to getting their own way, whether that violence is perpetrated by individuals or countrys attempting to liberate people from a person who equally believes in the use of threat and violence against his own population or not. They cycle of violence is not broken until each individual makes a conscious and personal decision to refuse to support it, this decision at the same time exposes those that leave the cycle to the danger of being abused with violence by those who have not yet made that decision. The greater good argument, is the only logical reason to retain armies, the idea of violence apllied somewhere against a small group may liberate and free a larger group repressed by the smaller group, or that without defence or the posiibility to apply violence we would leave ourselves exposed greatly to those that beleive in violence as a shortcut to winning a dispute.
Removing violence form the world is like getting everyone to do something in harmony together, stand up at the same time and agree not to use the shortcut that is volience.
