If religion has killed more throughout history people than WW1 and WW2 combined. why is still widely?

Because people still need something to tie them to this realm or rather keep their minds busy enough through their lives so they don't have to try to understand what else is out there and what's after death.

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.
