The main thing that I find upsetting is when they neglect a child or baby. If they kill themselves, that's one thing, but killing a kid by letting it starve to death because you were playing video games, is unjustifiable and despicable.
First you have the couple that let their baby girl starve to death because they were raising a virtual baby girl in a game, then you have that cow in Florida that killed her baby because he was crying while she was trying to play Farmville, then last week I read about a couple that sold both of their children so that they could have money for video games.
I love video games, but I love my daughter more, and she comes before games. For their crappy parenting skills, these people deserve to be thrown into a Saw trap.
