Yup sounds like one sick puppy.
What does it take to have a mindset like that? You just can't fathom what's running through their head really. Usually you could blow it all off as a mental issue of some sort but that sounds even more predatory.
It makes you wonder if their brains are wired up differently somehow or just genuinely sick in the head. There are some pretty dangerous people in this world to children. Lock up, throw away the key IMHO.
