There are several things wrong with jumping to that conclusion.
One: Your reference is based on an incident where the loss of life was
accidental, NOT intentional.
Two: It is ignoring that there may or may not be "civil" compensation in addition to a moral law ruling or that monetary compensation can be part of moral law (i.e. Deuteronomy 22:13-21) - so it is a major assumption.
Three: The Hebrew word for the child in the womb used in that scripture is:
yeled ~ Strong's
1) child, son, boy, offspring, youth
a) child, son, boy
b) child, children
c) descendants
d) youth
e) apostate Israelites (fig.)
and not referred to as:
pariy ~ Strong's
1) fruit
a) fruit, produce (of the ground)
b) fruit, offspring, children, progeny (of the womb)
c) fruit (of actions) (fig.)
Four: The reasoning you provide is tainted by the modern day mindset that "rights" equates existence; in scripture and today in various ways, locations, and extents - even an older child is subject to their parents, they have no "rights" as you refer to them.
It is also neglecting to acknowledge other references which reflect God knowing us
before we were formed, He being the one that
knitted us within the womb, referring to people such as
Isaac,
Jesus, etc. of doing and/or foretold existence before they are even conceived.
There are other references to children within the womb, but the difference between "our" abortion and scriptural would be that with our abortion, "we" decide to end the life; with scripture,
God makes that decision (i.e. Numbers 5:11-31 or 1 Samuel 15:2-4)
