code: '''
  Example script to automatically write a screenplay from a newsgroup post using agents with Crew.ai (https://github.com/joaomdmoura/crewAI)
  You can also try it out with a personal email with many replies back and forth and see it turn into a movie script.
  Demonstrates:
  - multiple API endpoints (offical Mistral, Together.ai, Anyscale)
  - running single tasks: spam detection and scoring
  - running a crew to create a screenplay from a newsgroup post by first analyzing the text, creating a dialogue and ultimately formatting it
  Additional endpoints requirements:
    pip install langchain_mistralai
    pip install langchain-together

  Are we talking about me, or the majority of the people that support it?
  Anyway, I think that "revenge" or "fairness" is why most people are in
  favor of the punishment.  If a murderer is going to be punished, people
  that think that he should "get what he deserves."  Most people wouldn't
  think it would be fair for the murderer to live, while his victim died.
  
  >Revenge?  Petty and pathetic.
  
  Perhaps you think that it is petty and pathetic, but your views are in the
  minority.

  >did a segment on capital punishment.  Each and every advocate of

  Where are we required to have compassion, forgiveness, and sympathy?  If
  someone wrongs me, I will take great lengths to make sure that his advantage
  is removed, or a similar situation is forced upon him.  If someone kills
  another, then we can apply the golden rule and kill this person in turn.
  Is not our entire moral system based on such a concept?
  
  Or, are you stating that human life is sacred, somehow, and that it should
  never be violated?  This would sound like some sort of religious view.

  Once a criminal has committed a murder, his desires are irrelevant.
  
  And, you still have not answered my question.  If you are concerned about
  the death penalty due to the possibility of the execution of an innocent,
  then why isn't this same concern shared with imprisonment.  Shouldn't we,
  by your logic, administer as minimum as punishment as possible, to avoid
  violating the liberty or happiness of an innocent person?
