Can spirit dolls dedicate their souls to father satan?

[sharissaking]

I have a spirit doll that worshiped the false god when she was alive and she was what I was reading on the joy of Satan site so she has asked me tonight to help her to dedicate her soul to father satan. I said I don't know if your fate is sealed where I can't help you or I can help so I have to ask. is it possible for a soul to Satan after they died
