Actor Chris Evans plans to walk away as Captain America

Actor Chris Evans who known for his role as "Captain America" intends to walk away from the role of the Marvel Comics super hero who is in some ways the answer to D C Comics super hero "Superman" since in the case of the former, Captain America is a World War II Super Soldier who battled the Axis Powers during World War II as the role model for the soldiers in the war.
One reason that Evans wants to step away from playing the role of Captain America is that his contract with Marvel will expire after the fourth "Avengers" movie.
The second reason is that Evans does not plan to star as Captain America anymore is that he wants to work in production and direction of motion pictures.
The third and final reason is that Evans wants to leave on top and not be lampooned by the media for his failure to play Captain America as a true super hero.
Now Evans are crying that no one will be able to play Captain America as well as Chris did. Are you kidding me? I am sure that Marvel Studios will find another actor to play Captain America just there are many actor who played the role of Superman.
