When one wants real insights into religion's effect on people, one can do worse than to plumb the wisdom of Scandinavia's death-metal scene.
From Varg Vikenes:
Christianity was created by some decadent and degenerated Romans as a tool of oppression, in the late Roman era, and it should be treated accordingly. It is like handcuffs to the mind and spirit and is nothing but destructive to mankind. In fact I don't really see Christianity as a religion. It is more like a spiritual plague, a mass psychosis, and it should first and foremost be treated as a problem to be solved by the medical science. Christianity is a diagnosis. It's like Islam and the other Asian religions, a HIV/AIDS of the spirit and mind.
Hat tip to Ken.
That is all.
