Abortion should be made illegal because many irresponsible people would take advantage of it. Let's say - A woman goes to a party, sleeps with a man, then takes abortion. Then get ready for another party.
That's just stupid, but it could be used if girls / woman have being raped. For woman, the child shouldn't be aborted because it's killing of a life. But young girls cannot concieve babies, so they will be in immense pain. Some families cannot afford to take care of the poor girl and her baby, so they might use abortion, even though they know it's killing of an innocent life, but what can they do?
