Some will say it is a burden (pieces of shit) and others will say it is a blessing to have them.
This is quite harsh. Please correct me if I am wrong, but I think it's safe to assume you have no idea what it is like to raise a child that requires such immense, constant support. I'm sure you know and like the persons you know, but you are not with them 24/7. You are not taking care of them 24/7, either. It is a colossal obligation and I applaud families that do spend the rest of their lives constantly taking care of the handicapped. But I also believe that it is natural to have feelings of burden. It is their entire life and daily concentration put into one entity. They have to forgo every freedom they otherwise would have had were it not for constantly taking care of the child. I would not call them pieces of shit, unless they were to neglect or abuse the child.
Onto the point of murder, assuming abortion can be deemed as such, you are saying you prefer a fetus develop the conscious and sentient ability to experience pain and suffering just to endure a lifetime of such pain and suffering? Wouldn't it make sense to curb the potential suffering by preventing it, before the fetus can experience it?
Additionally, what makes abortion murder? Is it the termination of life? The definition of life is already dubious and philosophically debated. How can we definitely make laws about something that is not widely agreed upon in the first place?
Do you consider viruses and bacteria living? According to the current scientific definitions of life, viruses are not alive since they cannot self-reproduce; they require hijacking the structures of other self-reproducing lifeforms (bacteria, animals, etc.). Does this make them lifeless? Do they have a soul? Do the lifeforms they hijack have a soul? The viruses are organic and move on their own, so shouldn't it follow that all organic beings are considered life? The definition of life is really quite hard to pinpoint. Following that, how can you be sure something is murder if you are not sure the victim is even a person, let alone "life"?
Ultimately, is a single cell a person? Where is the line drawn? Can a single cell even "suffer"? Does a life have to have x number of cells before being considered a person able to suffer? Is Plan B murder? Is male masturbation involving the death of millions of sperm murder? If we do not know the answer, how can we say what is or isn't ethical? How can we say what should or shouldn't, nay, CAN or CANNOT be done without fear of legal punishment?
