I believe that the prime reason is manipulation, but in my eyes (as a former muslim) muslims follow their religion in a conservative sense and I think this is the root cause. Tell me, if you believed that the Koran was the book of God and that it would lead you to heaven, would you not read it's every word fanatically? In essence suicide bombers are conditioned to believe that a few lines in their holiest book are the truth.
Even the word jihad has been manipulated - it is an inner struggle for faith as opposed to the militaristic ideologies you see today. Faith is not dangerous, it is the attitudes and ideas it provokes in order for someone to prove themselves. Whether it be prayer, pilgrimage or a suicide bombing - they are all a testament of faith, sadly enough.
Anyhows if there is a hell, bombers are sure going to be festering in the lowest of its pits.
Deprivation and torture. When someone got nothing to lose these things happen. Like in Palestine, if the Israelis kill the family of a guy and pull down his house, of course he will turn into a suicide bomber.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
