Hi New .. Welcome to the board
About the Satan thing, I kinda understand that going the "opposite" direction would make you feel great. It was my first instinct about twenty years ago. But the more I studied history and culture, I realized that "satan" was just another borrowed deity. Look up "the green man" or "forest god" or "pan" or "pagan deity"... you will find out some interesting things... most importantly that these deities do NOT represent what Christianity made them out to be.
Just take your time with the whole "devil" concept. You will find that your "brainwashing" that you mentioned is not limited to JW's.
In short New... the devil is another fairy tale, created to instill fear in those who are easily deceived. Without him... the JW's could not thrive. Without the "devil" they would have nothing to blame their problems on. If you become a "devil-worshipper" you will end up looking just as silly as those who are afraid of it. Just take your time. With any organized religion... there are always people with their own motives. Study the history of religions, and gods. You are free now to learn some real history... take advantage of it
