AR, I answered that question with the two that followed:
""What has been condemned as evil in the past when it comes to the destruction of any human life? How does society look on prior cases of any discrimination between the human rights of one human being and another?""
Society has at least nominally supported the non-maleficense principle of medical and social ethics/justice for over 2500 years. First, do no harm. If there is doubt as to personhood, give the human being the benefit of the doubt in protection from aggression by another. Increase, do not decrease the classes of humans that are considered persons, etc.
Look back at history. Contrast those societies which have a limited classification of "Person" and those with more wide spread protections for human life, liberty and property.
Which societies are healthier, more productive, and which are thought of as "good" by those societies that surround and follow them?
How ought we to live to increase the good in our society and the approval of those who follow us?
