Morality does not exist in nature outside of humans. There is nothing morally wrong when animals kill animals for any number of reasons in any number of ways. It is simply animals being animals. There is nothing morally wrong with what happens in nature.
When those same actions are committed by humans, there are moral wrongs that have taken place. Unlike animals killing animals, it is morally wrong for a human to murder a human or humans. We instinctively know murder is wrong.
Serial killers, even in the most Godless of places like the former Soviet Union, morally repulses people. Chikatilo was one such serial killer who caused outrage when word of what he had done finally leaked out. That outrage was a purely moral basis.
Wars happen in nature every day throughout the animal kingdom. Those wars are simply part of nature playing out. There is nothing immoral about those wars.
When humans go to war, there are rarely instances of neither side lacking moral justification. There are generally aggressors and defenders, which is what is happening in Ukraine and other places in the world.
Morally, war can be either right or wrong. It is morally wrong to invade another nation, but morally right to defend one’s country. There is no moral equivocation between the two.
There are times where neither side is morally right, in the case of certain civil wars or on a more global stage. Bad actors are known bad actors, such as the war criminal, Mengitsu, who slaughtered countless Ethiopians, from other socialists to the Jews, all were slaughtered by his command.
Since there is no morality in nature, there are no courts. Animals are not tried by animals, since they are incapable of committing wrongs. Right and wrong is a purely moral concept.
Humans have courts in every country in the world, some are just, and others are acts of immorality to punish a perceived immorality. Kangaroo courts, like what happened with the Soviets, was a clear act of immorality by an immoral government.
Where courts are considered fair and mostly just, both moral human concepts, they lie in democratic nations. Dictators do not have just systems, since fair systems of justice would limit their power, which they keep through recognizably immoral means.
When animals commit acts of cannibalism, it is seen as just one more part of nature. When humans commit the same act, it is a reprehensible act throughout the world. People are naturally drawn to call out the immorality.
That universal human morality, where even under the most oppressive systems of government, people know right from wrong, comes from God and is unique among humans in every way.
Since there is nothing like morality anywhere else in nature, it is clearly God-given to the whole of humanity.
Those who claim there is no God have no logical reason for why morality exists only in man. It has never been seen anywhere else in the world in any other creature. It is that morality, when acknowledged that it exists as an absolute truth, that keeps man from acting like animals.
Man’s inhumanity to man is unlike anything in nature, so to is the ability for man to live by an absolute moral compass.
