Wanton --- a cruel or violent action; deliberate and unprovoked.  The word fits.  

The piece in the Dallas Morning News says partial birth abortion doesn;t happen in the 9th month, and that any abortive procedure in the 9th month is a C-section.  But in a C-section, the baby is born alive taken out alive.  Obviously, that is not the purpose of a 9th month abortion.  Today's Operation Rescue names five places in the US where a woman can get a 9th month abortion even now.
