Final answer:
The biggest tragedy, as referenced by Luttrell and defined in Aristotle's theory, is when a character of high status falls due to an error or flaw (hamartia), not wickedness, evoking both fear and pity in the audience.
Step-by-step explanation:
According to Luttrell, the biggest "tragedy of all" would be the spectacle of a virtuous man brought from prosperity to adversity as this scenario would neither arouse pity nor fear, but simply shock us. Instead, Luttrell explains in referencing Aristotle's definition of tragedy, the most potent form of tragic narrative involves a character of noble stature who is not perfectly good or evil but whose downfall is prompted by a great error or frailty known as hamartia. Therefore, the tragedy lies in the misfortune of one who falls due to a mistake rather than wickedness, eliciting both pity and fear in the audience, and achieving the cathartic effect that is the hallmark of classical tragedy.
