I know there are some non-Christian's who like the idea's a concepts from Christianity. Like the 7 deadly sins or book writers like J.R.R. Tolkien like the Lord of the Rings series. I get. It shouldn't discourage anyone? My game dev university has the audacity to speak historical art pieces of Christian content, like the Western art history class. Even though the school is a polytheistic secular college, I am glad my university doesn't talk rubbish of anyone's faiths that has to do with art.
I get you. That should not separate a friendship relationship between religious people and non-religious people. But the 7 deadly sins are a concept borrowed for other beliefs like greek mythology to be aware of humanistic behavior of wrongdoings and deeds. And Anime shows.
I am looking forward to your work. Greet you the best for your games and business.
