I Was a Teenage Werewolf (1957)
Dr Hugo Wagner: But you're sacrificing a human life!
Dr Alfred Brandon: Do you cry over a guinea pig? This boy is a free police case. We're probably saving him from the gas chamber.
Dr Hugo Wagner: But the boy is so young, the transformation horrible -
Dr Alfred Brandon: And you call yourself a scientist! That's why you've never been more than an assistant.
Det. Sgt. Donovan: It's not for man to interfere in the ways of God.
Dr Alfred Brandon: I'm going to TRANSFORM him, and unleash the savage instincts that lie hidden within... and then I'll be judged the benefactor. Mankind is on the verge of destroying itself. The only hope for the human race is to hurl it back into its primitive norm, to start all over again. What's one life compared to such a triumph?
