No, the UCC does not "support" abortion. No one wants women to have an abortion. Like Pope Francis, we believe that abortion is always a tragedy, and that women in this situation need mercy. Also, along with Amoris Laetitia, we believe in the primacy of a woman's conscience in determining the least evil choice in a difficult situation. Even when there is objective sin, there are always mitigating factors which remove culpability--read Canon 1323.
