The Randomness of Bad, Human Bit-flipping

My sister, Robyn, has lung cancer. Some part of that diagnosis is related to randomness. I have diabetes, there's some randomness mixed in there. My Prius had a computer problem, once again some randomness. The truth is that in each case there's a proximate cause, but the actual resulting problem doesn't happen each time.
In the case of my sister and I, our behavior made us more susceptible to disease, but randomly some people are never afflicted with the disease. It's never "fair" or "undeserved" or a "shame", it just is. Knowing that despite my behavior, my disease is not the hand of some malevolent god working to try my essence is very reassuring and empowering. Now I don't have to worry about any "moral" component, just the treatment. Same with my sister's cancer, behavior set it up, but randomness selected her for the disease. She was never justified in believing that despite evidence and science, she was immune to the effects, but the observed randomness of the effect, lured her in.
The problem with the Prius was apparently the corruption of the core memory of one of the computers that run the engine. Several unrelated error codes caused the computers that monitor the other computers to go into protective shutdown. The memory scan logged the fault codes, but the errors were not verified physically.
The question is, "What corrupted the memory chip?" Everything from static electricity to nearby lightning to some radio frequencies have been shown to cause "bit-flipping". Engineers have found solutions for all those, that's why computers can be trusted to handle delicate life-threatening tasks like launching the Space Shuttle.
What they haven't fixed yet is the random high-energy particle or cosmic ray that zaps a bit two. We haven't figured it out with people yet either, but of all the systems we've devised to fill in the gaps, science has worked the best. Over the decades, science has eliminated causes from demonic possession to the evil eye, but people still cling to explanations that blame them for a random process.
That's just another service that superstition and religion provide. They set us up to believe that since we feel guilty about bad things happening, maybe we can somehow ingratiate ourselves with the univers and avoid bad things. It has never worked.
Billy Graham, Mother Teresa, all the Pope's except one, Adolf Hitler, Jesus,and my sweet innocuous Aunt Ruby all died. No negotiations possible.
And that is not the grim, existential death sentence that it seems to be. It relieves us of responsibility for the random portion. The rest of the behavior we can understand and cope with.
