Not wanting to wade in on either side here.
My own view is that God gave us a life, which we are responsible for and should treat responsibly.
Here's a point for consideration:
John 15:13 – "Greater love hath no man than this, that a man lay down his life for his friends."
That may be so, but to wilfully give up one's life – is that not suicide?
If God is the sole arbiter of life, then it's not 'my life' to lay down, no matter how noble the reason – and yet we have examples of just such nobility of sacrifice, and we don't condemn nor believe God condemns.
If I develop the most painful cancer, is that not God's Will. What right have I to seek medical intervention?
My uncle, like many, many others, died of an incurable debilitating illness. In the end treatment was 'palliative care', meaning make the patient as comfortable as possible. In my uncle's case, as it is, I'm pretty sure, in the majority of cases, what actually tips the balance is not the illness but the treatment, the painkillers administered to manage the suffering. The final morphine dose.
Take that palliative care away, and the suffering can be much, much worse, and go on much, much longer.

One can go on splitting hairs ... but it seems to me there's a moral dimension.

I'm not saying abortion is right. I don't believe an embryo is 'just' a bunch of cells – it is destined to be a human being, and should be accorded rights, in the same way that someone, no matter their degree of impairment or disability, is still, nevertheless, a human being – an ill-formed human being, just an embryo is an an un-formed human being.
Nor, however, am I saying it's always wrong.
The mother-baby thing: Continue with this pregnancy and both mother and baby will die. Terminate the pregnancy and the mother will survive. That's a tough decision for the mother.
Heart transplant? What right have we to swap out the heart?
I'm saying we live in a world defined by contingency, a fallen world. And maybe, just maybe, God allows us a degree more self-determination than we sometimes allow.
I hope so, if not, we're just puppets, and then love takes on a much darker aspect ...
