It is awfully sad.
I knew there would be sympathy for the mother on here and thoughts along the lines of "what was going through her mind?" and "she must have had some mental health issues." All perfectly reasonable to say.
Contrast, though, with the MAN who jumped off the hotel balcony with his children last year, who obviously also had similar issues. It all all "selfish bastard" this and "evil monster" that. Oh, but you see, did I mention he was a MAN? You're allowed to say that kind of thing about big nasty evil MEN.
