I care about all of you and desire the same for all of you, but Alice in particular plays with demons for entertainment and knowing that demons are real can be a first step in starting to believe in Jesus. I believe this is how Faethers came to be saved as well
Demons are just the ideas of men and women, they are present within us all, but to call them demons is to deny the humanity behind those ideas as if they were something outside of ourselves. To play with demons for entertainment isn't really any different than choosing to live a normal life.
It's those who say demons are 'evil' that are stuck within a mindset of Slave Morality, and those who'd deny themselves the very things that make us human don't desire to truly live.
