Final answer:
Abortion is considered morally wrong by some due to the belief that a fetus is an innocent person with rights, thus making abortion equivalent to murder. This stance is often rooted in religious or philosophical convictions regarding personhood and the sanctity of human life. Other perspectives, such as Warren's, argue that the fetus lacks rights and personhood, prioritizing the rights of the pregnant person.
Step-by-step explanation:
The moral objection to abortion often upon the debate over personhood and the sanctity of human life. According to one argument, abortion is considered morally wrong because it is viewed as the intentional killing of an innocent person, equated to murder by those who believe that a fetus at any stage of development is a human life with rights equal to the mother. This perspective is often informed by religious and philosophical beliefs about when life begins and what constitutes personhood, as well as a societal value placed on the sanctity of human life, which might be seen as a slippery slope leading to the justification of other types of killing, like euthanasia.
Conversely, some moral arguments, such as those by Warren, suggest that a fetus does not have rights or personhood, and thus, the rights of the pregnant person are paramount. This contention is supported by views on individual liberty and bodily autonomy, further enshrined in legal precedents that protect the right to seek an abortion before the fetus is viable outside the womb. Normative moral theories and societal views, however, vary greatly across cultures and are also reflected in the laws and practices related to abortion, with some countries restricting it and others allowing it under certain conditions.
