Uh oh another abortion question???

how is it women justify killing their unborn babies? from the moment of conception on the genetic make up of that person is set. From , eye color, hair color, personality etc. Especially when God plainly states that he knows each individual from an embryo? Suppose it only took 3 months gestation for a human being before they were ready to come into the world...making them small similiar to a baby kangaroo or koala bear? they would be a tiny living breathing creature totally dependant on the "love" and care of their mothers. Would it be so easy to chop the poor little things head off? Really how do you justify this? The whole thing is beyond me. If it were my choice i'd see to it that each "aborting" individual served the same prison time as someone who murdered a full grown child or person.
