In literary terms the “modern hero” has a chosen image of self and position and the tragedy results when the character’s environment denies the fulfillment of this self-concept.
In other words the modern hero sees himself as ideal but in reality others perceive him to be the opposite.

For example Kramer is a modern hero because he sees himself as a helpful and kind person, but in reality others see him as bothersome.

What is a particular episode of Seinfeld where it is mainly about Kramer and he exhibits traits of being a modern hero? I have to write 7 pages about this.
