Thats a jolly good question, because if I believe in the bad guy, I have to believe in the good guy too. Hmmm, its a kind of celestial catch 22.
All I can say for sure is that KH did a superb job of making me believe in the bad guy, because I have spend 80% of my life being shit scared of him. But it did a rubbish job of making me believe in the good guy, because I can take him or leave him. I dont feel any strong feelings either way regarding his existence.
Can I swap de debil for Santa, and god for the tooth fairy?
