You are so very welcome, Sir, too :-)
Still I think neither of you has done anything wrong. In some cases, there are such utterly, dreadful choices are the only option.
All that can be done now is to pray.
I lost my little nephew 12 years ago (due to a genetic defect, too, but he eventually passed in my SIL’s womb due to natural causes, just weeks before the birth date) and it’s still sore.
The year after, my mother passed away from brain cancer, and my father never got over the loss of his wife and grandson. He spent his twilight years taken care by a nurse and by me, until it was “his turn” - at least he passed on with a blissful smile on his face.
Sorry for this OT comment, but I must admit that it isn’t always easy for me to be “strong and carry on”. This is why I have so much sympathy for all those who have to say good-bye to their loved ones :-(
But still I believe that the words in the Good Book are true, and one day we shall meet all of our loved ones again in the splendor and glory of the Heavenly Jerusalem, Zion, the City of our God.
Amen.
