It is an evolutionary trait that will reflect in all sorts of places as the society becomes more complicated and then even more. Nobody had to worry about suicide bombers before someone thought of inventing bombs or religion or institutions to promote either one of those. And those institutions were not created with an end goal of suicide bombers, they were created with 'good' thought, ultimately to make the creator look more important and powerful. I hope you get the gist of my argument.

Regarding my comment being sexist - true. But one has to acknowledge the differences of sexes before aiming for equality.
