Invoking deontology is not an answer to a question about utilitarianism.
However since you seen more in line with deontology let us discuss how it perceives abortion.
Deontology is the ethics composed of Moral Duties and Moral Rights.
Positive Duties are actions that if unfulfilled leave everyone capable of fulfilling them guilt of wrong doing.
Negative Duties are actions that if taken leave the actor guilt of wrong doing.
Positive Rights are like a Positive Duty
Negative Rights are like a Negative Duty (Example: A Negative Right from theft is similar to a Negative duty to not steal)
There are arguments about whether Positive Rights/Positive Duties can exist. Certain theoretical Positive Rights absolutely cannot exist.
(You cannot be entitled to 1/Nth of a scarce resource if there are more than N people)
The deontological discussion on abortion begins with:
What is the characteristic that qualifies a being for Moral Rights? [Moral Personhood]
Is the right to life a Positive Right, a Negative Right or fiction? [Right to Life?]
Then we move into the Violinist example. [The Violinist]
Let's assume for the moment government granted fetus' human rights. How would you describe the woman's motive for killing the child?
Here is a list I have come up with:
1) Her motives are selfish and therefore her act is immoral.
2) She has an obligation to make sure her child does not suffer in life, but does this allow for someone to decides someones life?
3) She needs to be alive to care for her family. This can be both selfish and caring. Again, just because you care about someone, does that give you the right to control their life?
After some research I also found how to relate the consequences (I forget the name of the material it's called) to this topic.
Example: She wants to keep her child away from suffering...but that can lead to even worse problems (Just like Sethe from Beloved).
1) Abort the baby (Sethe killing her child), problem is later in life you develop a mental illness and become suicidal/a murderer out of guilt for aborting your baby. Now, you have caused a lot of damage in society.
2) Have the baby: a) she dies, and we discuss the points listed above b) lives, but is a single mother. Now, this family will barely be able to support itself and thus experience a lot of suffering. Doesn't the mom have a right to stop her children's suffering? If so, why not kill her children? Stop their suffering, and loosen her suffering? Again, we run into the selfish possibility and if the mom has the right to control someones life, even if they are children.
Parents discuss parenting in this way to me: you are given the job as 'parent' to make sure your child grows up well. Just because they may not be able to handle suffering yet (grow up to be killers cause of this), doesn't mean we 'silence' them. We work with them to help them persevere. Maybe, suffering is what makes us stronger. Maybe it's good to suffer. Again, this is the opposing side to suffering is bad.
Still, we also run into the problem if the fetus again has moral rights. So ASSUMING they DO, how would you answer this? ASSUMING they for sure DO NOT, how would you answer? If we don't know/unproven which is the reality I believe, how do you answer.
