Do you believe in demons?

I believe that the Devil exists because God is real so, if you believe in God, you know the Devil exists too.

Wow, so many arrogant "know it all" around here. It's easy to blame mental illness or shit like that when you never experienced it. People who experienced it don't talk with such certitude and those who do are simply deniying it to feel better. I don't need to feel in a confort imaginary world and pretend that science can explain everything and make the fucking ignorant claim that "it's all in your heads because if you can't see it or explain it in a rational way" it doesn't exist.
