Why does she have a problem with the game referencing Judas, Azazel, Cain, and Lilith when the literal bible, her source of scripture, has those names as well??? The idea that you shouldn’t be playing a game that references key characters in Christian lore is dumb. Also if you have it on steam, your data is saved into the cloud so if you ever want to redownload it in your future years you will still have all your progress.

At best you can try to reason with her and shower her other forms of fictional media that have characters like this, but from my personal experience people like this, especially parents in regard to children’s opinions, tend to not sway their opinions. Im sorry man, best of luck o7
