Edwin (Predators)

Edwin is a villain in the move Predators. He's a doctor and a serial killer. He tortures his victims to death. He lacks any real weapons and only carries a scalpel, but his knowledge of poisonous plants allows him to immobilize his victims. At times he seems to be a coward or at least amoral, begging others to help him but not helping those who risk their lives to save him. While it would appear this is simply a lack of care for life, he begs Royce to not kill him when Royce finds him out, perhaps indicating some sort of flawed superiority complex.
