I am not sure of this thread has become somewhat blurred whilst the two aspects are of course connected the morality of abortion is different from the legality.
Now as damyanti points out here in Europe when life begins is clearly defined and there have been several test cases and more recently in the UK a parliamentary debate on this subject. We know legally when life begins and therefore when it is legal for a woman to have a termination.
This is not up for debate, or in any way questionable.
Now the morality issue, hmmmm tricky one, and of course dependant upon ones own judgement, this is quite simply the only answer here.
No one else can possibly impose their feelings or beliefs on the woman considering a termination, it is down to the individual concerned, end of.
Ones own moral code may well be representative of or reflective of the society in which one is immersed or educated, however it is just that at the end of the day, ones own moral code.
I have never been involved in such a decision, but have no doubt what so ever that the decision to terminate has never been reached without much soul searching or lightly.
Only the woman concerned should be able to make such a choice free from peer and social pressures.
