I was not making a statement on the specific child in the article, I also mentioned that the environment is often the most important factor. I am just raising the fact that in some cases it can be a mental disorder, and it is not about deciding who is born bad, but assessing correctly every situation so you can do the greatest good, and protect yourself. I think we agree mostly, maybe my original comment could sound reductionist to some ears, but I tried my best to convey that I was pointing out a rare scenario, specifically to counter the arguments that you can’t have this sort of mental disorder at the time of birth. It is important to point out, otherwise innocent parents will get harmed (not those in the article, obviously)
