Its not another persons life.
I just want to point out another interesting thing.
Natural abortions happen all the time, the body decides all by its self that it no longer wants to carry the baby for a variety of different reasons.
Perhaps the body is under a lot of strain, not getting enough nutrition, sick etc
There are also several checkpoints where the fetus is evaluated and if its not growing fast enough or not developing correctly it will just reject it.
It really sucks when this happens, especially if your heart really wants a baby but if the body can choose for its self not to carry to term then why can't the mind.
Its not moral decay - its nature.
There is no such thing as a natural abortion. In context, the term refers to the intentional or negligent termination of a pregnancy by killing and extracting the foetus. Miscarriage is something else.
But whatever word you choose, the substantive moral and legal issue concerns human intentionality because this requires human agency.
Miscarriages, ie
natural failures to carry the child to term, are not morally and therefore legally significant precisely because they do not arise from human intentionality.
The intentional or negligent killing of innocent humans is always morally wrong. That is why our positive law also places decisive importance on intentionality.
(Why the qualifier "innocent"? Because it's required to cover the case where an aggressor is killed in self-defence, ie where the only way to stop the aggressor is to use defensive force that results in the death of the aggressor, who in this case is not regarded as innocent.
In no possible way can a baby in the womb be regarded as an aggressor against whom force may be used in self-defence.)
