If I assume that she authored the piece sincerely rather than as some navel gazing intellectual and virtue signaling exercise, then it isn't a shock that her child has a defective comprehension of right and wrong (or at least was atypically vulnerable to having one installed by others-- e.g. utilitarian consequentialism and 'effective altruism').
