Crime Shows

My hb is so into crime shows like forensic and investigation discovery. I watch with him from time to time, and it can be riveting sometimes, but I would grimace in disgust at how some people could be so cold blooded to have the guts to commit such gruesome crimes. The cold case show that we just saw a while ago where two young men massacred seven people working in a restaurant not for money but just for kicks is so beyond me. How could one hurt let alone kill somebody just for the excitement of it? You would think these people could be vicious meth addicts who are mentally deranged and so not in their right mind kicks to commit such a crime. But to kill just for kicks is so unthinkable!
