Five Soldiers in Suicide Bomber

In this article, I read about how five soldiers died from two suicide bombers. They weren't conniving for they were walking by foot straight toward the base. The first bomber set off and the second followed after right at the military checkpoint. I don't see why anyone would atrophy their life for something that would never come true. It is said that if they blow themselves up, then they will get 72 virgins in heaven. Having 72 virgins wouldn't be capacious, it would be hard to breathe, a bunch of people around you all the time, no privacy whatsoever, and no time for you and just on of them since they would always be around. And if that is the case, then heaven would be crowded and it would be bad for the claustrophobic people up there. I guess being a suicide bomber is the pinnacle their so called career.
