In no way whatsoever am I saying that abortion and capital punishment are morally equivalent. What I am saying is that conservatives could make a point where liberals are forced to acknowledge that if capital punishment is wrong than abortion must be as well.
I believe it is fine for people to believe no one should be killed because there are other ways to deal with extreme criminals (life in prison, justice and the law is upheld), that is their choice and belief (Absolute pro-life). But, it is morally wrong to believe individuals should have a sole right to terminate anyone's life for any reason. Killing someone in legitimate self-defense is one reason why someone would morally just to kill someone else, in a just war as a soldier would be another case. It is never permitted to kill innocents.
Why innocent children should have to pay with their life for the so-called "mistakes" of others is beyond my comprehension.
