First of all... no... that is not how you define a human in this subject.
Second: There is indirect thought between on this topic and thing which defines a human about what makes a choice, as a choice, in our lives.
Tertiary aspect is that while we are set in certain conditions, requirements and definitions, each for individually, that is not however what makes us as a human.
What my point is, is to go further and deeper thought about what and why, certain actions are taken for each part in this discussion.
After all, there is a reason why you even started a forum topic, which contains a subject about abortions. Another reason definitely is to enhance your vision about what and why people have, their thoughts set on this, regardless of any reason.

The issue is not about your answer, as your answer is also correct, but it is not the correct... umm... "calculation statement". I did read whole thing and it contains all required variables to give a certain answer, but that is not proper way to tackle it in brain chemical level.
