Some people never grow out of the phase where they have imaginary friends. It doesn't sound as weird when you call it God.
It's crippling i think. That friend follows you wherever you go and applies "moral" leverage to any of your decisions. You aren't free to be yourself, you're trapped in a box you created for yourself. Some people feel comfortable hiding in that box b/c they're scared of the world and feel safe retreating inside of it. Or maybe they're scared/ashamed of the person they would become if they didn't have that box to hold them back.
It's sad. "Morality." Haha please. Don't make me laugh.
