Do you remember anything from when you were an infant?

You might as well say that it is justified to kill a baby. In addition, born humans are just as much of a clump of cells as fetuses are. You might follow up by saying that the clump of cells that exists as a born human actually has organic functions that prove life, but the same is true for a fetus, because a fetus has organic functions that allow it to receive oxygen, receive nutrients, grow and develop body parts, and react to sensory stimuli, just like anyone who has been born. My sources for the claim that fetuses have consciousness and can feel pain are listed below.Fetal pain: a systematic multidisciplinary review of the evidence - PubMedhttps://pubmed.ncbi.nlm.nih.gov/16118385/The emergence of human consciousness: from fetal to neonatal life - PubMedhttps://pubmed.ncbi.nlm.nih.gov/19092726/Physiology, Fetal Circulationhttps:ncbi.nlm.nih.gov/books/NBK539710/
