[M]any atheists, while critical of theodicy, are themselves engaged in a kind of secular theodicy—an attempt to reconcile their optimistic views with… - David Benatar

A charmed life is so rare that for every one such life there are millions of wretched lives. Some know that their baby will be among the unfortunate. Nobody knows, however, that their baby will be one of the allegedly lucky few. Great suffering could await any person that is brought into existence. Even the most privileged people could give birth to a child that will suffer unbearably, be raped, assaulted, or be murdered brutally. The optimist surely bears the burden of justifying this procreational Russian roulette. Given that there are no real advantages over never existing for those who are brought into existence, it is hard to see how the significant risk of serious harm could be justified. If we count not only the unusually severe harms that anybody could endure, but also the quite routine ones of ordinary human life, then we find that matters are still worse for cheery procreators. It shows that they play Russian roulette with a fully loaded gun—aimed, of course, not at their own heads, but at those of their future offspring.

Humanity is a moral disaster. There would have been much less destruction had we never evolved. The fewer humans there are in the future, the less destruction there will still be.

A few of my critics have claimed that I am committed to the desirability of suicide and even speciecide. They clearly intend this as a reductio ad absurdum of my position. However, I considered the questions of suicide and speciecide in Better Never to Have Been and argued that these are not implications of my view.
First, it is possible to think that both coming into existence is a serious harm and that death is (usually) a serious harm. Indeed, some people might think that coming into existence is a serious harm in part because the harm of death is then inevitable.
