Gender equality. In most cases it takes a man and a woman to conceive a fetus. But if the fetus is finally born into a baby, the consequence of that is rarely divided evenly between the man and the woman. In extreme but not really uncommon cases, the division can be 100%-0%: that the man bears no consequences at all and the woman bears all the consequences. Abortion makes the consequence close to 0, so that it's more even between 100% and 0%.
