No, because a pregnancy always carries a risk. The percentage of the risk does not change that fact. I'll try to illustrate. " Say I see someone drowning in my pool. Do you think I am obligated to risk my life to save that person? Would my obligation change if I'm a very good swimmer?" In my view, no. I still would be risking my life. What amount of risk of death is acceptable enough to compel a person to take the risk? As to personal accountability of pregnancy. I assume that a person wanting an abortion did not plan on getting pregnant. They made the choice to have sex, not to create a baby. Yes they might be stupid, or irresponsible, or simply unlucky. None of that tough is sufficient enough reason to demand of someone to risk their lives.
