This discussion isnt limited to abortion per se.
The question is, is the idea that a fetus does not equal a full fledged life, an immoral one.
clealry the answer is no, and Ive provided several rayahs to that end.
Including Ubar yerech imo (regardless of context), that a preganat woman is killed with her fetus if she is chayav misah, that there is finacial payment for killing a fetus etc etc.
As mentioned above this does not mean abortion on demand is mutar. Just becasue a fetus is not a life doesnt mean we can kill it, for any number of reasons. (Some of which would probably make Avram sadder than a fetus being “just a foot”, eg some say it is hashcasas zera)
and yes some shitas do apply chavala to abortion eg Maharit chelek 1 97,
