It's murder no doubt about that imo, but it's justified murder. Killing is wrong, but procreation is also wrong, arguably even worse. Ideally you would want to avoid pregnancy in the first place, but short of that I think abortion is justifiable.
I'm not "pro-choice" though, I don't think anyone should have the choice to procreate. But obviously that isn't going to be an option, so we should limit the legality of childbirth to foids in monogamous marriages.
