From Jeff Jacoby's "Massacre of the innocents" in the Globe Columnist / March 16, 2011:
The civilized mind struggles to make sense of such savagery.
There are those who believe passionately that all human beings are inherently good and rational creatures, essentially the same once you get beyond surface disagreements. Such people cannot accept the reality of a culture that extols death over life, that inculcates a vitriolic hatred of Jews, that induces children to idolize terrorists. Since they would never murder a family in its sleep without being driven to it by some overpowering horror, they imagine that nobody would. This is the mindset that sees a massacre of Jews and concludes that Jews must in some way have provoked it. It’s the mindset behind the narrative that continually blames Israel for the enmity of its neighbors and makes it Israel’s responsibility to end their violence.
The truth is simpler, and bleaker. Human goodness is not hard-wired. It takes sustained effort and healthy values to produce good people; in the absence of those values, cruelty and intolerance are far more likely to flourish.
