Okay, I understand what you're saying now, but I strongly disagree.
To me it sounds a lot like just another human concept used to explain (what I consider) the human concept of morality. I think it is a philosophic/cultural/religious way of thinking about it, but certainly not a scientific one.
If morality was the constant of nature you believe it is I don't see any reason why our morality would have changed in the massive ways it has throughout human history and still varies so much around the world.
There are still hundreds of millions of humans around the world who hates homosexuals with every bit of their "soul"/mind, who don't have even a tiny bit of empathy for gays who are killed or tortured. The vast majority of humanity is still eating animal meat, most without much worry about the well being of the animals. Torture is still commonly used and justified around the globe, even by very intelligent Americans [1].
Considering how much what we consider moral/immoral varies/has varied through history around the world I don't see any reason to believe it is a constant of nature. It seems muuuuch more likely to me that it is determined by our cultures and societies than by nature, otherwise you would expect to see much greater similarities.
You are conflating ethics with morality and choice/action with effect.
The question posed was why do Bad things happen to good people? You noted that, from I assume a scientific perspective, bad things are just often random occurrences that people artifically label as "bad." My response is that Bad things are not random and result from a deviation from the natural order and that our sense of that wrongness from those deviations is not supernatural.
To put it in a more realistic scenario (I only used torture previously because even non-human species have been shown to avoid and punish torture). Let's say I begin to suffer from chronic dehabilitating headaches and these headaches force me to stop doing the charity work I have done all my life and I become depressed to the point of contemplating suicide. I have no family history, genetic disposition, history of drug abuse etc. What I did do was build a house in 2002 that used imported drywall from China containing volatile chemicals that have been emitting sulfurous gases, carbon disulfide, carbonyl sulfide, and hydrogen sulfide which have been absorbed into my body altering my chemical makeup ever since.
Is it by a random path that those molecules found their way into my body? Or is it a result of the actions of people disregarding their sense of wrongness? Yes. Am I also free from fault? No. Because I am part of and have benefitted directly from a culture that values paying the least at any cost and doesn't properly price environmental damage/costs into the marketplace. I could have built my house smaller for example paying a higher price for building materials.
I could speak to your other example of discrimination by sexual orientation in the context of natural law, but I would face immediate downvotes and this isn't really the place for that discussion.
We will just have to agree to disagree that human ethics hasn't really progressed that much in the last few thousand years. Natural law persists but what humans value obviously alters over time. That is, how strictly a culture decides to punish acts of torture of animals is a reflection of the culture, not evidence of its wrongness or the nature of the act. Personally, I believe that the slower rate of progress in removing Bad things from happening is largely that say unlike physics or chemistry, there is no way to improve the pedagogy of morality. With the introduction of mathematics and the creation of a universal language for scientific understanding progress at a remarkably faster rate was achieved in the last few hundred years because it is easily transmitted between generations. The only way moral education is imparted from generation to generation is by example. You can't educate morality beyond telling stories and parables and living by example so positive changes more in accord with natural order are limited in scope by time and geography.
I think if you surveyed those people who justify torture in our time if torturing their children was wrong, you would find overwhelmingly that that they would say it was, but that they believe they have a right or should be able to do it to "others" based on some circumstance (such as they did some other Bad act). Doesn't mean they know that the act of torture is any less contrary to the natural order or that it won't have consequences as a result, just that they are choosing to value something else greater (and, wrongly I might add). Similarly if you asked someone eating an omelette how it tasted before and after you gave them the experience of the conditions in a factory chicken farm, you would generally get a very different response. It has been shown actually to alter the perception of the taste of food in subjects and induces disgust, that is how tuned to the natural order humans are.
You contradict yourself by saying that bad things are a logical result of multiple events and then saying that you "could" have done something different. Our brains are just a bunch of chemicals that form organic materials called neurons that process and share information using electric-chemical reactions called synapses. Meaning that if you are a murderer you are as responsable for killing as the sun for shining (that doesn't mean we shouldn't lock murderers aways, please don't bring that argument).
