Dirius, you might know the answer to this....uncomfortable question--Can a devout Catholic, as Kavanaugh appears to be, countenance legal abortion? Because if not, then he's lying about it.
I don't think you can encase a person into a single specific ideology just by using one word. Many catholics, such as myself, are
pro-
legal abortion.
Not because I like the practice or recommend it, but rather because banning abortion seems pointless to me. In my country abortion is prohibited, except for few specific cases (as a result of rape, or if pregnancy can endanger the life of the mother, etc.). Yet, unlicensed clinics and physicians perform abortions in a clandestine manner, which has lead to many women loosing their lives over the years from complications caused by unsanitary conditions. In the case of wealthier families, they simply fly to another country to have it done.
So personally, I'm in favour of legalised abortion, because it is going to happen anyway. Better to save one life, than loose two. As for your question, Kavanaugh may have his specific reasons, but I think I'm offering you an example in which permitting a practice does not imply you think it is right or that you approve of it.
EDIT: what I do agree with the pro-life movement in your country is that you need to repeal Roe V. Wade and have a proper constitutional debate in congress about it, and either ban it or sanction it by law, not by the courts.
