Violence is there in most of us all along. It can be triggered by desparation. It can most easily be triggered by a more violent person or group threatening us with torture or death and getting us to do stuff we would not normally dream of. I think that is how most tragedies have occured..in Germany, Cambodia, etc. A very small group threatens more people, gets them to go along, the size of the group increases, it is harder to stop the movement. Then you have a genocide. Most people do not rise up against others willy nilly....The sooner you break the cycle the better. Heads have to probably crack to do so but you save countless lives in the long run...hopefully..you never know what can be unleashed. Either way. mg
