I feel for the family, the loss is all the worse because of this. To make yourself feel better, go read some of the textbooks they were taking to "school". You know, the ones that teach that they must spill their blood for the liberation of Palestine, and how they will all get Virgins and Feasts besides rivers of honey for having done what they were raised to do. Die as propaganda points. Personally I think raising my son to not play in the front lines or with explosive devices like the Jews do is smarter, but to each his own.
Are you suggesting that schoolboys choose their textbooks? I don't doubt these boys were being propagandized by the PA. That only makes them doubly victims, and in no way mitigates the criminal indifference to human life of those IDF elements who placed a deadly hazard in their way.
