The pro-choice argument is saying that fetus in early stage cannot have a right to life. we have to define the term equality. This term represents how humans should be treated and how different people should be treated differently,
based on their needs and interests. Humans have a right to life and the pursuit of happiness, which means that those rights are really basic and we should all be able to get them. Equality will help us explain and understand pro-choice argument, because a fetus cannot have any sufficient and moral characteristics to claim a right to life. It means that fetus cannot know that it basically exists and that is why no rights are violated. Besides, right to life should focus more on morally relevant characteristics instead of living. Those sensations are sensations of pain, pleasure, taste or smell and make human life valid.
