Regression As the human race ‘evolves’ and progresses it has created an environment unsuitable for the generations to come. This Darwinist environment promotes the ideals of a ‘dog-eat-dog’ world‚ in which one person’s ambitions are more important than another human being’s.

Comparing Real Vs. Movie Commodus In the movie “Gladiator”‚ Emperor Commodus is portrayed as an unstable and neurotic sadist who killed his own father for the throne of the Roman Empire.

author to not only entertain the reader‚ but to teach life lessons. These themes strongly relate to real life in a myriad of ways‚ so much that it’s barely a challenge to think of an example of a theme in a real life situation.
