to the above post:
you know that things like these will probably never stop right?
Not if you have that attitude. If you don't care about the lives of those around you, then you will almost always effect society negatively. But if you started to truly care about people (and not just people, individuals), changes in their lives will occur. The impact you as an individual might be small, but if enough people cause enough positive impacts, the change will be great.
Nobody will stop this sort of thing on their own, and one event won't stop it either. It won't be stopped in the course of a day, and it probably won't be stopped in the course of a few years. However, it's something that can be stopped, and just for that reason, we should at least try. Otherwise we become the cause of the problem.
