Am a Muslim and also agree with your thought. It has become a prejudice belief that it is the devil that make us do bad things, and once upon a time i also believe that it is so but then i ask my self, if devil is the source of evil then why do people commit atrocity in a place of worshipping God?. This prove that it is not devil making us do bad things but it is a doing of our choice, because i believe that an evil entity or devil can't prevail in the presence of God. Thanks for the post am also a fan of the series, can't wait for the next season.
