Gun violence and almost every other problem in our society
Can largely be blamed on the death and interment of empathy. I don't blame guns, video games or mental illness for most ill behaviors. Whether it's a shooting spree or a CEO's malfeasance; road rage, workplace bullying, a smiling thumbs-up by a torturer; or sickening attacks on women, minorities and the impoverished during election season, they all come down to the same root cause: the utter lack of human regard for your fellow travelers.
Barring a fundamental change in our culture, expect to see these terrible days to continue for the foreseeable future.
