In Your Own Backyard

Where do people's minds go when they do henious things? I just read today about a Texas couple who had their baby's body stored in their FREEZER. Police do not know yet if the baby died from being put in the freezer or was dead and then put in there, but either way, what were they thinking? Another couple, in the news just today, tried to SELL their baby on EBAY. Tell me how people can somehow turn off their moral compass long enough to do something like either of those things. It just makes no sense, and is scary to know you live in a world where things like that can happen. Everyone says it can't happen to me, but you never know what's going on right in your neighborhood, or even in your own home some time.
