Question: **Are Catholics free to disagree about whether it is prudential to not forbid abortion by law?**

Namely, can a Catholic ever take a position, that abortion should remain legal for any reason (for example forbidding abortion by law would not stop as many abortions as some other strategy would in which abortion remains legal)? 

Or maybe, can a Catholic take a stance that it is not prudent to make abortion illegal at this moment, but that we should continuously strive for that, and after definite time make it illegal?
