Is it ok to believe in Alignment as faith (Dungeons & Dragons)?

I wrote a 55 page essay in university ethics class in January 2000, on alignment (Dungeons & Dragons) ethics, personality, and the enneagram. My faith was Roman Catholic and I decide what is good and evil from the alignment (Dungeons & Dragons). I was told not to go too deep or lest I get lost. What do you think? Should I put away the D&D and go back to church? I’m going to do my own thing anyway but I would love the discussion. I would like to go deeper into the subject and write a book about it and make it my career.
