An enemy for which even the Taliban are no match

I was reading today that 23 South Koreans were kidnapped by the Taliban while travelling in Afghanistan. The first hostage they killed was the pastor of a church, but - get this - his family, even though his body was returned to them, refuses to hold a funeral or even a memorial service for him until the Taliban release the other 22 hostages.

I am convinced this degree of altruism and love simply is not possible for humankind alone to achieve. Even in the face of imminent torture and murder of their own father, brother, husband or son, these people simply cannot be broken. It leaves me utterly awestruck.
