Rats, one of my favorite creatures. They can eat through a 150 lb body in about four days. They just need to be motivated. Starve a couple of hundred for a few weeks and they will mutilate a body beyond recognition. Watching someone getting devoured by rats is a sight to behold. My victim doesn't deserve any sympathy. Humans in general do not. I feel pity for the rats. Human flesh tastes horrible. 
Blood drips on a tile floor. Remnants from a fresh kill. It's easy to pick up a person, invite him back to your motel room for some action that will never occur. The only action is the snuffing out of his pathetic life. This person has no idea that I know him completely. This victim is totally readable. His mind is an open book to me. I know his darkest thoughts. If I didn't pick him up first, he would have raped and killed someone else. Then he would have slept liked a baby lying in their blood. Instead, he will breathe his last breath and understand what type of monster he was to this world. Right before I send him to nothingness. 
Mr. Squirrel, he sees my deeds. Unloading the carefully packed bundles of human carcass and burying them in the ground. This one is going to bed for eternity. She did enough damage to the world when she was walking free on this earth. She ruined countless of lives before I stepped in and ended her reign. Yes, sometimes we serial killers exterminate our own kind. I guess we hate the competition!
