That sentence was uttered, not by a terrorist suicide bomber, but by a child actor in the notorious video "No Pressure". [see this, h/t Jack]
The parallels are disturbing: Children and young people from different walks of life being brain-washed into being willing to sacrifice their lives for a cause.
For another parallel, see this, about some veiled threats against atheists from some Christians in Oklahoma [from Ted Frank, no link available].
I understand and agree with the need to teach children and youngsters the importance of principles and morality. But killing and threatening to kill those who disagree with you is rarely, if ever, defensible (I was a pacifist for much of my life). I much prefer competition in marketplace for ideas.
