Remember when people used to react normally when life didn't go their way? Nowadays, this seems to be the natural reaction: "An unhinged man involved in a bitter child-custody battle tossed his toddler son to his death from the roof of a 52-floor building on the Upper West Side Sunday, then killed himself by jumping, law-enforcement sources said.Dmitriy Kanarikov, 35, of Brooklyn, was supposed to drop off adorable 3-year-old Kirill with his estranged wife at 1 p.m. at the 17th Precinct station house on the East Side after a three-hour visit, as per their custody arrangement, sources said." They'll probably make excuses for this "father" and demand more millions to help "mentally ill" people. But this isn't mental -- it's deliberately spiteful and it's evil, a way of saying "Well, I'll show YOU!" Let's just hope he suffered, and the baby didn't.
