Abortion and Religious Freedom
What really makes abortion restrictions immoral is that they violate vital freedoms including freedom of conscience and freedom of religion.
The existence of degrees of im/permissibility of killing makes it clear that in truth we do not accept rules like, “Thou shalt not kill,” in their literal sense. Such overly simplistic formulations leave out important factors and pretend there is an absolute answer where absolutes are usually impossible. In other words, details and circumstances matter in moral judgements.
