The goals of guns are not always to protect, guns are invented in order to KILL. Yes it is really to kill certain people and even animals. There are only few people who using guns to kill animals or what we called modern hunters. Right now, the majority of the people who have guns are meant to kill each other. The world is changing but the humans doesn't, the history will repeat itself and for sure there will be another war that will happen because of the guns and ammos.
