Greetings my lady . Should have known you would further my argument ;-). First , let me deeply explain myself . The possibility of mental deconstruction is for all human beings in theory. However, as you have mention, it is not mentally healthy for some. Therefore , it is impossible for all human beings to be mentally deconstructed from their religious ideology .
Thus we have some for reasons I can not
explain , that are born Satanist/atheist . This is much like someone who no matter what they are told by society, will choose to have an alternative lifestyle.
They would say , " I was born this way." How much different are the Satanists/atheists? In the aspect of choices in an individual's life , there is no difference.

"Satan represents man as just another animal, sometimes better, more often worse than
those that walk on all-fours, who, because of his "divine spiritual and intellectual
development", has become the most vicious animal of all!"...Dr. La Vey
