One of the biggest points is that people have to take responsibility for their actions. There are so many situations such as teenage pregnancies where people are just enjoying themselves without thinking about the consequences. Living that kind of life is not ethical. Here, not only are they hurting themselves, but also they are hurting that zygote that could be a potential human being. .
People who are for abortion, utilitarians, have valid points too. They believe that a child is a result of a loving relationship. What is a woman supposed to do if a pregnancy is the result of a rape? Is she supposed to keep the child then too? If abortion is necessary to save the life of the mother, then abortion in this case is morally right because you will not be intending the death of an innocent person. You will be, in fact, intending the death of a "guilty" person. That is, a person guilty of endangering this life of another. In this case, the abortion would be considered self-defense, which is acceptable even in "murder" cases. It will not be murder, it would be self-defense. Another argument is that potential people's rights cannot be of more importance than people who are already living. How can we argue that people's rights are of lesser value than that of living beings who do not exist as of yet. These are the basic arguments for abortion.
In this case, I personally think that abortion is really a woman's choice. It is true that the fetus is a person to be and all, but the question we have to ask ourselves here is whether or not that child will be able to have a proper life when he or she comes to this world. I have always believed that giving birth is not even a drop compared to bringing up the child, which is an ocean. Take instance the case of rape. How is a woman supposed to keep the child of the man that she does not even know? What if the woman is a fifteen-year-old girl? I"m not saying that abortion is always right.
