Hm. I'm not attracted to any specific deity, either from religious texts or works of fiction. I'd say some sort of Bizarro version of Azathoth nobody wrote about. Screw this "Crawling Nuclear Chaos" nonsense, I want to approach things in a positive light.
I'd go for something that's similar to Azathoth, but that symbolizes raw potential, pure creative force. Something that, ideally, has no real intellect to speak of, because otherwise you've got yet another judgmental asshat who'd threaten to smite my ass just because I didn't adhere to some obscure set of rules.
I don't believe in this concept that we've got some sort of atonement to do from Day One, and I certainly don't buy into hardcore Christianity's notion that God is a vengeful idiot with an itchy trigger finger or a particularly heavy Banhammer. I might not believe in this stuff outright anymore, but I remember my religion classes telling me God was basically love personified. Vengeance, wrath or it being possible to displease him never entered the picture for me, as I was told that God is basically tolerance past all forms of tolerance. He was supposed to be this guy who'd never judge and who'd understand that hey, living's kinda hard at times, man. It isn't always easy to make the right choices, you know? Thinking that God's there to smite the wicked is really a roundabout way of saying you've got anger or intolerance issues; because the fact is we've all been "wicked" at one moment or another in our lives.
At least, in my humble opinion. Make of that what you will.
