About 25 years ago I attended a seminar presented by a retired US Army general. He pointed out that it is very difficult for most people to be motivated to kill another human being. This is a very real problem for the military. In a combat situation many soldiers 'freeze up' in various ways. Some simply refuse to shoot, others will shoot but not at the enemy and some others will simply go through the motions without actually firing their weapon. For example, following the Battle of Gettysburg approximately 11,000 unfired muskets were recovered. The vast majority had been loaded and reloaded sometimes over a dozen times but had never been fired.
In the mid 1950s following the Korean war this officer was tasked with finding a way around this problem. As a psychologist he decided to try desensitization techniques. Recruits were shown professionally prepared extremely graphic films depicting military actions that included soldiers being wounded and/or killed.
Did this approach work? Yes, it certainly did as witness the Viet Nam War. Some American soldiers were desensitized to the point that military discipline was broken and mass killings of enemy civilians occurred.
So, what was the point of his presentation? He pointed out that desensitization actually works very well but it is no longer limited to military training purposes. The population, particularly the young and most impressionable, are now being exposed to movies, TV programs, comics and video games that are far more graphic and brutal than the military films that were prepared under his direction.
His concern was very simple and straightforward --- we are in the process right now of desensitizing an entire population to violence and death. It should be no surprise to us at all when we see young people brutalizing and killing each other sometimes on a large scale.
Is this a problem that we should be concerned about?
I think so.
