We can only weep for the scores of children massacred by the Taliban in Peshawar, Pakistan.
Just a day before this slaughter, another Islamist took innocent cafe patrons hostage in downtown Sydney. Two of them were killed, along with him.
Not long ago, Islamist extremists took the lives of two Canadian soldiers in Ottawa and Montreal.
When will this religious madness ever end?
Just when we consider beheading by ISIS to be the worst inhumanity, we learn the Taliban butchers made pupils watch their teacher being incinerated.
In this competition of evil, we must now wonder who has cultivated the most brutal brand: Boko Haram in Nigeria, ISIS militants, al-Qaida or the Taliban?
