If abortion were illegal it would force poor women to bear and raise children they can't afford to bring up. It would force young women to raise children when they are still children themselves and would cause many deformities when incest is in involved. There would be a number of unsafe abortions in back allies. It would also force women to give up their dreams and stay home to bring up babies. Worst of all, it would condemn victims of incest to carry and nurture the offspring of their rapist.
Abortion is necessary for women to have control over their own bodies and life.
I wouldn't have made it to medical school. I was married at that point to a very ill man and it would have been terrible to have to have my baby. It also gave me another chance of my life and gave me back part of the pride that a person stole. To ignore the rights of others is selfish. Women must have the right to control the functions of their own bodies.
