The "If taking of innocent life is wrong...." had nothing to do with pedophiles. The argument is that of the Law and State. Murder is the removing and/or killing of innocent life. And that is the Law of the State explicitly describing that as a crime. And hence why the debate is reasonable. The lifeform is human in all developmental stages which an infant is born and proceeds from their mother's womb - the life is human. Essentially why it is debatably wrong to take the life of a human being developing through all stages from zygote-to-embryo-through fetal development to an infant. Which is why it is a serious matter  to take away such a life through abortion. Thus, not a religious argument, but that of the Law and State.
