Abortion, on the whole, is a 'necessary evil', IMO.
There will, of course, be women who suffer from infertility in later life - who regret abortion during their younger years. But, for the vast majority, I imagine, there is an overwhelming sense of relief that they do not have to give birth to a child that they cannot give loving and willing care to.
I'm waiting for the 'adoption' view but this, IMO, is fraught.
