There are so many sick and mean people out there. It is a fact that people that are dangerous as adults (serial killers, etc) start out by torturing bugs, then graduate to small animals.
Several years ago someone in Alabama took a family's beagle and skinned it while it was still alive. Poor little thing made it back to it's family, but didn't make it. I still think about poor Annie all the time. A reward was offered, but they never found out who did it. That sicko is still out there somewhere
