They're your children, and you're emotionally involved - it's an emotional decision. It's the oldest dilemma in the book, and is not dissimilar to the 'who do you save from the oncoming car - your child or your wife?' question.
Ethics (via Latin ethica from the Ancient Greek ????? [f???s?f?a] "moral philosophy", from the adjective of ???? ethos "custom, habit"), a major branch of philosophy, is the study of values and customs of a person or group.
It covers the analysis and employment of concepts such as right and wrong, good and evil, and responsibility.
It is divided into three primary areas: meta-ethics (the study of the concept of ethics), normative ethics (the study of how to determine ethical values), and applied ethics (the study of the use of ethical values).
Your post states that “and she gave me a brief but fascinating insight into the world of ethical dilemmas”. Your post is quite frankly pandering to emotional inept. Once again it’s the intelligenceia trying to belittle the common man
