Let’s be clear, I am a Catholic. And I do find abortion utterly regrettable and a form of social ill. Nonetheless, I’m not in favor of governmental restrictions upon abortion.
When someone is drowning we would not punish you for deciding not to take the risk to rescue that person or use some other means to force you to rescue them. Even if, you were the only person there and not rescuing them would inevitably lead to their death. Even if it was your fault they were in the water eg. you accidentally nudged them in or even pushed them in as a joke. (Short of intentionally trying to drown them from the outset)
The analogy here is rather obvious. What then would people who are in favour of governmental restriction of abortion say?
