I don't accept your premise of what a fertilized egg is. Being human, IMHO, is defined by our brains not our DNA.It's not a question of punishment, that's bullshit. It's a question of the right to live vs the right to end a life that you yourself irresponsibly created. People make mistakes; IMHO they should pay for them rather than passing it off to someone else. Which in this case is an unborn child.
Which should have precedence, the right to live or the right to kill for convenience sake?
And BTW, where's your empathy for the dead unborn baby? Mama gets to move on but the aborted baby doesn't.
