Don't I know it. Many years ago at church camp we had a torturer. He would pull all the legs off of crayfish in the camp stream, smash any bug he saw, good or bad and toss anything that moved and wasn't human into the campfire just to watch it die. When we discovered him about to do his mojo with a box turtle, my friend and I had seen enough and roughed him up but good.
A bit hypocritical, I suppose. But he stopped his crap.
Nothing like getting a taste of your own medicine.
