Now I am in personal conflict on the topic of Edwin (the doctor) now according to most things I read online and such it says he's a sociopath or cannibal or whatever, now fine, but I not think that's right and apparently the quote that I possibly miss hear is "I'm a murderer, I'm a freak, but here among the monsters I'm normal" the way I hear it and really it makes more sense I think is "I'm not a murderer I'm a freak" see in my view there are different scenarios that things work, but I tend to think along the lines of the 'twilight zone' episode 'eye of the beholder" where he was born on an alien or possibly bred or born on the predator planet, and when he says among the monsters he isn't referring to the predators but the humans, but well I may be thinking well out and beyond the box but I can do that from time to time, anyway I think my theory is better especially considering he is working with the predators as a mole but well let's see what others opinions are
