Doctor Waldman: You have created a monster, and it will destroy you.
Henry Frankenstein: Dangerous? Poor old Waldman. Have you never wanted to do anything that was dangerous? Where should we be if no-one tried to find out what lies beyond? Have your never wanted to look beyond the clouds and the stars, or to know what causes the trees to bud? And what changes the darkness into light? But if you talk like that, people call you crazy. Well, if I could discover just one of these things, what eternity is, for example, I wouldn't care if they did think I was crazy.
Henry Frankenstein: The brain you stole, Fritz. Think of it. The brain of a dead man waiting to live again in a body I made with my own hands! With my own hands.
