That depends on the stage at which the lief is taken.  I know of no relevant, onteological distinction between a late-term fetus and a new-born baby.  So your question is convertible to:  "So you would want to punish a woman who has killed her two-day old baby?"  I say, "In a heartbeat."  To acknowledge the value of human life, to protect human life, I say, in a heart-beat.  At least when the baby is late-term.  What have we come to when we cannot even say this?
