Apparently animals need to be tricked into the slaughterhouse. An animal is trained to lead them inside.This is known as the Judas Goat (or Cow, Pig etc.). In exchange for its betrayal, the animal gets a lazy, longer life. But it leads me to wonder if the animal knows what it has done. If it realizes that it was the only animal to survive the trip? Does it remember? Have a conscience? Does it think of suicide?
