Actually, this one is a combination of culture and religion.

Nazir Ahmed appears calm and unrepentant as he recounts how he slit the throats of his three young daughters and their 25-year old stepsister to salvage his family's "honor" -- a crime that shocked Pakistan.

The 40-year old laborer, speaking to The Associated Press in police detention as he was being shifted to prison, confessed to just one regret -- that he didn't murder the stepsister's alleged lover, too.

The headline on the story is: 'Honor' killings shock Pakistan.

I don't see it in the above-referenced article, but another one I remember reading put the possible punishment for this crime at anywhere from 10 years to death by hanging. If this monster gets anything less than death, then I'd say that Pakistan was never really "shocked."
