Rufus: He still digs humanity, but it bothers Him to see the shit that gets carried out in His name - wars, bigotry, televangelism. But especially the factioning of all the religions. He said humanity took a good idea and, like always, built a belief structure on it.
Bethany: Having beliefs isn't good?
Rufus: I think it's better to have ideas. You can change an idea. Changing a belief is trickier. Life should malleable and progressive; working from idea to idea permits that. Beliefs anchor you to certain points and limit growth; new ideas can't generate. Life becomes stagnant.
