The Jehovah?s Witnesses have their opinions on how the world was and how it will be - one day. To achieve this they endorse the idea of mass genocide.
None of this is reality. The world has always been a violent and dangerous place for humans and Animals. It is the nature of the corporeal world. We all have the capacity to be creative or destructive. Most people don?t have to rely on the violent side of their nature as we live in a very organised system - at the moment. You only have to upset the average motorist to see how normally calm people can become aggressive and violent.
Only in a non-physical world that vibrates at a much higher level, can we be free of the restrictions of physical life.
