There is duality everywhere my friend, if there is black there is white, if there is good there is bad too my friend, when there is God there is Satan too my friend. Evil things are all work of Satan. Satan is clever, he tricks you to do evil things. In terms of atheists, I don't know what's wrong with them, they just don't believe in faith. Have faith my friend. If God shows up in true form like in Mahabharat, atheists will either go mad or shit his pant right there, If God shows up in avatar form, then atheists will question what is that? It's a choice of duality believe it or not.
