I've often had similar thoughts. Actually, this is kind of my answer to the old philosophical question of "If God exists, why does He allow bad things to happen?" If we think of him as a writer, then the answer is obviously "Because it makes the story more interesting." Though I guess that's hardly reassuring. ^^;;

And you probably shouldn't worry too much about being a useless secondary character. I mean, normal writers have to focus on only a few main characters, but one would think that God would have the ability to give every character an important story, I guess.

Also, your use of Lemony Snicket's image for this secret amuses the hell out of me. XD
