Even though the subject was stated as "evil", I can't help but root for it to break free. Somehow, I interpreted the "darkness" and the "devil" as desires and passion that society somewhat shackled. The emotions and thoughts that societal norms force us to keep locked up. I don't consider the liberation of those things as "evil", in fact, I think it's our right to let them loose in the world. Fly, demons, fly!
Thank you for reading my work and leaving such nice words!
