How long does the fertilized egg need to be implanted before you deem it worthy to be a life?
If I jump in front of your car and you hit me and kill me, by your definition it is murder because you chose to drive the car down the road even though you KNEW someone might jump out in front of your car at any time.
No, that is illogical. The person jumping is responsible for their own fate. The new life from conception has no control over their fate. The mother has the responsibility to care for that life. Your argument is more akin to a man throwing a baby in front of a car and then blaming the baby.
