ethics in an unethical selfish world are totally complicated. Morality however is not. I will live by my morals because they are grounded in the good of society instead of self. Simply stated, what part of thou shall not kill is not ethical? It is easy to see it is immoral to kill a human being, no matter what stage of life it is at. Unethical “ethisits” argue it is ethical to kill some to create one, or heal one, or kill one who’s life is not deemed worth living. This is in complete disagreement with moral teaching. As Ronald Reagan once said, the only ones who argue for abortion are those who were not aborted. Same applies here.
