You're not serious!?! They were warned to get out. (One would think two weeks of all-out war would be a clue.) If you life and you family's life were at stake what would you be waiting for? a limosine?
In Islam there can be no greater reward than martyrdom. The perfect martyr, or ash-shahidu, has either been slain in a religious war or slain unjustly. There is no wailing over the kids who died (except in the West where no one should ever die), because they have received a blessed reward.
