Individual decision must prevail. There can not be an agreement on whether a fetus is a living being or not. It is all in how we define it. Many harsh words are spread between the lines on this issue, and niether side really tries to understand the other- or maybe they just can't.
I personally think that abortion should not be a guiltless endeavor, because that could desensitize and create a cold society. But it rarely is a guiltless endeavor. And because we cannot come to any agreement, we must leave it to the choice of the individual. Someone who does not view a fetus as living cannot understand it as murder. Someone who sees the fetus as a living being cannot understand how it cannot be seen as murder. I simply see it as a sad choice for someone to make, but their choice nonetheless.
