Sometimes it is a selfish decision I guess. I would never try to argue that people cannot be selfish. The law does not govern fairness or selfishness, or else the government would step in to balance out the wealth inequality. A person does have a right to their own body, period. We just cant force a person to donate their body to support another life. Thankfully billions of people willingly donate their body to carry a fetus to birth, but there are some who do not and that Is their choice. I do believe it is more important that people, men and women, have bodily autonomy, than to force every women that gets pregnant, to give birth.
