To each his or her own? Absolutely. We all are responsible for the dogmas or beliefs by which we choose to live. As to the supernatural, well there is evil and there is good in this world. How we relate to that depends on belief systems we choose to adopt. More so when we realize we are not 100% good.
I know you have said your decisions are set in stone. Openness to new knowledge, however, is never a bad idea. There was a time when people thought the earth was flat. Evidence convinced everyone otherwise. Even in the path you have chosen there is room for growth. We cannot grow, however, when do not allow room for possibility there is much we do not yet know.
Again, all the best as you navigate life. I hope you travel well, live well, end well.
