Abortion and Preference Utilitarianism when the ovum is fertilized, there you get the essence which has the potentiality of development in somebody like you. There is life, human life and killing an innocent human life is normally against every constitution
, which defends it. There you see that legal abortion, except extreme questionable cases and situations which are not the rule, is not logical, therefore technically illegal. As you can see, I am rather focusing in human life and that is sufficient to discard abortion. Person as a concept is tricky, malleable and used to confuse and not to talk about the real thing. Human life begins at the conception, legally, biologically, philosophically, as you can prove by studying yourself.
