Complete Monster: Victor Frankenstein, in contrast with every other interpretation of the character, is a heinous individual who gradually loses every redeeming quality he had as the films go on. A Mad Scientist obsessed with life beyond death, he plunders graves to get the parts to make his monster, and has no compunction committing murder to cover his tracks. Defined by his utter separation from human morality after a point, Frankenstein begins to gain the parts by simply murdering people and harvesting them for resources. His worst moment is when in Frankenstein Must Be Destroyed, a later film in the series, he rapes a woman for nothing more than his own satisfaction, proving his only devotion is to his own desires above even science.
Jerkass Woobie: The creature who is violent but probably only because his brain was damaged and later because he is thoroughly degraded by Baron Frankenstein.
Moral Event Horizon: At first, Victor Frankenstein seems to be an obsessed genius, even after actually killing a man to get his brain but when he uses the monster to kill the maid he's banging to keep her quiet, he's now irredeemably evil.
