If the penalty for even an accidental case [of abortion] is so severe, it is obvious that a deliberately induced abortion is very strongly forbidden. It is not necessary to ban deliberate abortion, since it is already eliminated by this law. Second, if a man who, in the course of a fight, unintentionally bumps a pregnant woman and causes her to abort, must suffer the death penalty, how much more so any person who intentionally induces an abortion?
