Peter Singer is one of the few atheists who nearly tries to live what he believes, yet I would dare say that even most atheists would find his views on human life objectionable. Here are a few goodies expressed by Singer, from Dinesh D'Souza’s article Atheism and Child Murder.
On how mothers should be permitted to kill their offspring until the age of 28 days: "My colleague Helga Kuhse and I suggest that a period of twenty-eight days after birth might be allowed before an infant is accepted as having the same right to life as others."
On why abortion is less morally significant than killing a rat: "Rats are indisputably more aware of their surroundings, and more able to respond in purposeful and complex ways to things they like or dislike, than a fetus at ten or even thirty-two weeks gestation."
On why pigs, chickens and fish have more rights to life than unborn humans: "The calf, the pig, and the much-derided chicken come out well ahead of the fetus at any stage of pregnancy, while if we make the comparison with a fetus of less than three months, a fish would show more signs of consciousness."
On why infants aren't normal human beings with rights to life and liberty: "Characteristics like rationality, autonomy and self-consciousness...make a difference. Infants lack these characteristics. Killing them, therefore, cannot be equated with killing normal human beings."

Whatever one thinks of Peter Singer’s radical belief system, at least he is consistent (to a certain point).
