I honestly don't understand how someone who cares for children who have terminal illnesses is helped by having a god belief. I would be very angry at this god who was giving cancer to innocent children. One would think that oncologists would all be atheists, or maybe deists. What excuse do they give their god for making children suffer? "God works in mysterious ways". I guess that's it.
I don't think one need resort to "mysterious ways" to be able to answer this question.
I do not believe in God. I do not accept any evidence offered nor this as any form of evidence of God. It's just not there, as close as we have tried to look.
It doesn't need to be there.
That said, do you think it's evil to turn something like our universe "on", feed in some garbage in the first Planck second, and just watch what happens, and let that be the glorious complicated mess it is,
assuming you don't know what that will be?
It's not evil.
It's just not good, either.
If it's a "universe" of things evolving towards the completion of a mathematical model of their system, then it's going to be harder before it's easier, and more approximate before it is more precise. That's the only way such a thing can ever be:
It will contain misses and there shall be tragedies.
If you want to discuss the reasons why some entity might do that, maybe you should ask, "do humans have an interest in creating systems and simulations hosting objects that operate so as to complete mathematical models of their system?" And "what is that interest in such generalized problem solvers?"
Is there interest in making such a thing as a universe in a bottle?
I dare say there is.
When humans run such things, often the behavior is not great... although when humans kill simulated children on purpose, at least they tend towards instantaneous methods.
As such there may be things like child enslavement simulated directly, because maybe whatever the goal is, is to create something that has an experience of such pain as losing children, so that were they to ever meet us they would be able to grasp upon empathy rather than find our pain an alien concept to them.
There are reasons why, and they are not mysterious.
You're in the "won't forgive God if it exists" camp. I'm over the hump on the "I'm going to be the thing that some of the entirely synthetic things won't forgive if it exists".
My own reasons are simply that I live in a universe where kids get cancer, and that the unguided evolution that gave rise to me carries no guarantees of cancer-free existence, and anything I unleash into the world needs to actually be capable of understanding that kind of suffering and hating it for what it is, while accepting that it was always going to be so and could never not.
There aren't necessarily gods. I don't believe there are any. There are zero or more. I think that these facts are rather good reasons to focus on solving our own problems, and just not worry about thinking about gods except where such thoughts help us solve our problems.
I think instead we should accept that
Gods are unnecessary except for engaging in hypotheticals that help us solve problems and create models, and in which case they are recognized still as purely hypothetical!
