At least you dropped the fictitious “citations” this time to non-existent cites in the Babylonian Talmud.

The Jewish view:

in the Talmud appears to provide an exception for abortion when the life of the mother is at risk. It could be interpreted as “self-defense” but that is not what it says.

The relevance of this to a Catholic viewpoint is unclear. The Jews did not share our view of Man as body and soul, nor did they have any clear idea of an afterlife.

I am unaware of any moral calculus acceptable in Catholic teaching that would provide the basis for weighing the moral “goodness” of one death versus two. However, in Catholic moral theology an intrinsically immoral act cannot be justified by citing a “good end”.
