This paper explores sentiocentric antinatalism, which is based on two principles: (1) prevention of the emergence of pain and (2) antispeciesism. It argues that the notion that all sentient creatures, including humans, should not be born presents an unsolvable paradox; the paradox is that the antinatalists who attempt to eliminate all births of sentient creatures must bear the obligation to survive for the purpose of preventing the emergence of all other creatures in this world. There are four phases to their attempt, and corresponding to them, there are four obligations that antinatalists should bear in pursuit of their ultimate mission. In the last part of this paper, the paradox of antinatalism is compared to the paradox of time travel, and their similarities and differences are discussed. In addition, antinatalists' obligations are discussed in terms of supererogation.
