It’s the doctrine that says that because of our father Adam’s sin, we are all sinful beings from birth. Every human sins and is totally affected by sin. This is how the Bible explains it in Romans 3:10-19,
“None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good,
not even one. Their throat is an open grave; they use their tongues to deceive. The venom of asps is under their lips. Their mouth is full of curses and bitterness. Their feet are swift to shed blood; in their paths are ruin and misery, and the way of peace they have not known. There is no fear of God before their eyes.” Now we know that whatever the law says it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may be held accountable to God.
It’s not a popular teaching. Most humans like to believe they are basically good with some character flaws, if that. There are even some inside the Church who fall prey to this kind of thinking and begin to question the goodness of a God who would send people who are “basically good” to an eternal Hell.
What I find most baffling about this is that outside of a religious context, humans freely condemn themselves when they are honest. Take this article from the secular site Listverse,
“Have you noticed that most history books divide eras among major social, political, or disastrous events and that the lion’s share of these are wars? In 200,000 years of the modern human species’ history (our personal history), the only thing we’ve been able to do consistently well is kill each other. All animals fight, but only humans wage war. We are the only species that has ever existed on Earth to have attempted the elimination of entire species. And we are always getting better at it, always pushing scientific knowledge, and almost always one of the first things for which science is put to use is the invention of new methods of murder.
We do it so well that we cannot even face ourselves when we consider it. We devise euphemisms, especially in time of war: it’s not murder – it’s combat, or “defending our freedom,” “target neutralization,” “justifiable homicide,” “soldiery,” “just following orders.”
The human is the only animal ever known to be capable of revenge, hatred, or sadism, and we are intimate with all three. We kill for every reason.
Black powder was originally invented by Chinese alchemists looking for the elixir of life, then used as a means to set off fireworks for amusement. That didn’t last long. Now it is more commonly called gunpowder.
The Wright Brothers pioneered human aviation for the purpose of enabling aerial warfare, because in their opinion this would make national invasions impossible, and would thus negate all warfare in the first place. Wishful thinking. Tesla envisioned his “death beam” for the same purpose. Einstein had no idea his Special Theory of Relativity could be used to split atoms for the purpose of killing people. When Robert Oppenheimer and Enrico Fermi explained to him what was being done at The Manhattan Project, he burst into tears.
Consider all the kindhearted, nonviolent people through the ages, Jesus, Gandhi, Martin Luther King. What do we do to them? Hate them, harm them, kill them out of spite.
The human is an unnatural animal because of all this. It does not fit into any environment, except perhaps the urban environment. We think of ourselves as predators, usually with a sense of pride. Nevertheless, on even terms, the human would not stand half a chance in a fight to the death with most of the other entries on this list. But that only incites us to pick the fight, and we do so by the one method in which we have no equals: thinking. Given the proper preparation (typically guns), we are more than a match for any other organism on this list. And that fills us with malicious and/or “sporting” glee.”

Romans 2:14-15 says
For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them on that day when, according to my gospel, God judges the secrets of men by Christ Jesus.
We are all rebels against God. Our rebellion against all that is good and right is before our very eyes on the news every day. We make excuses and attempt to justify our own evils, but our recognition of others only serves to prove we are, as a race, evil to the core. The only hope we have is found in Jesus Christ. He paid the price on the Cross for all rebels and God proved it by raising Him from the dead. Anyone who has the Son has life, anyone who does not have the Son of God does not have life.
