Assuming that each couple has three children, an original pair's cumulative descendants over ten generations amount to 88,572 people. That constitute… - David Benatar

It would indeed be wonderful if there were a beneficent God who had created us for good reason and who cared for us as a loving parent would for his or her children. However, the way the world is provides us with plenty of evidence that this is not the case. Imagine you were to visit a country in which the evidence of repression is pervasive: There is no freedom of the press or expression; vast numbers of people live in squalor and suffer severe malnutrition; those attempting to flee the country are imprisoned; torture and executions are rampant; and fear is widespread. Yet your minder tells you that the country, the “Democratic People’s Republic of Korea,” is led by a “Great Leader” who is an omnibenevolent, infallible, and incorruptible being who rules for the benefit of the people. Other officials endorse this view with great enthusiasm. There are impressive rallies in which masses of people profess their love for the Great Leader and their gratitude for his magnificent beneficence. When you muster the courage to express skepticism, citing various disturbing facts, you are treated to elaborate rationalizations that things are not as they seem. You are told either that your facts are mistaken or that they are reconcilable with everything that is believed about the Great Leader. Perhaps your minder even gives a name to such intellectual exercises—“Kimdicy.” It would be wonderful if North Korea were led by an omnibenevolent, infallible, and incorruptible ruler, but if it had such a leader, North Korea would look very different from the way it does look. The fact that many people in North Korea would disagree with us can be explained by either their vested interests in the regime, by their having been indoctrinated, or by their fear of speaking out. The presence of disagreement between them and us is not really evidence that deciding the matter is complicated. Not all of earth is as bad as North Korea, but North Korea is part of “God’s earth”; so are Afghanistan, Burma, China, Iraq, Saudi Arabia, Somalia, Syria, and Zimbabwe, to name but a few appalling places for many to live. Even in the best parts of the world, terrible things happen. Assaults, rapes, and murders occur, injustices are perpetrated, and children are abused. Fortunately, the incidence of such evil in places like Western Europe is lower than in worse places on earth, but my point is that they all occur within the jurisdiction of a purportedly omnipotent, omniscient, and omnibenevolent God. Nor should we forget the horrific diseases from which people suffer around the globe, or the fact that every day, billions of animals are killed and eaten by other animals, including humans.

[M]any atheists, while critical of theodicy, are themselves engaged in a kind of secular theodicy—an attempt to reconcile their optimistic views with the unfortunate facts about the human condition. There are many secular theodicies. One of the most commonly expressed is that the bad things in life are necessary.

It is unlikely that many people will take to heart the conclusion that coming into existence is always a harm. It is even less likely that many people will stop having children. By contrast, it is quite likely that my views either will be ignored or will be dismissed. As this response will account for a great deal of suffering between now and the demise of humanity, it cannot plausibly be thought of as philanthropic. That is not to say that it is motivated by any malice towards humans, but it does result from a self-deceptive indifference to the harm of coming into existence.
