What motivates a person to kill innocent children? What is the level of the suicide killer's motivation and desparation?
I think Islam is the only religion through out the whole human civilization which glorifies death. The moment a person is born, he or she is made to believe that life after death is better than life itself.
No wonder, weak-minded people fall prey to this philosophy and break all the connections with the life on earth, and dream about the unknown-phase-after-death.
