Why is violence so prevalent in Western culture? Sure, there will always be disagreements which turn into fist fights or an occasional shooting. But more and more frequently, we hear about people trying to resolve their problems at school by shooting it up, or their family problems by killing their family. It seems that the violence is being escalated even beyond what an out-of-control angry person would do. Often, these incidents involve at least some planning ahead of time.
It has gone beyond natural rage.
I think this at least partially explains it, especially the mention at the end about most people learning reflection, empathy, and identifying with others. I think technology often plays a large role in stunting the development of these because it holds our attention often for long periods of time, limiting our social interactions. In fact, it often replaces our interpersonal interactions with artificial surrogates which have no relevance to interpersonal reality.
