Murdering the innocent is wrong. Geneticly the child is made up from the DNA of the mother and father. The child isn't a clone of the mother. It has a unique DNA structure that is distinct from it's mother and the child is not the mothers body. We tell people all the time they don't have a right to choose to murder another human. Was it right when the government let blacks be killed because they were seen as not human? We all depend on others during our lives. When the baby is born and a mother doesn't want to bother to feed the child and lets the child die it is murder. At what stage of life do you want people to say you need to die, at birth, toddle, handicapped, old age. Murder isn't allowed to feel good. Murder isn't allowed to make your education better. Killing someone innocent because you were wronged or hurt is still murder.
Sometime a choice to save only one life has to be made. In this case life is the issue not murder.
Act responsibly, don't be selfish in sex and then selfish in murder.
