Hypothetically, having a villain murder the family of a hero isnt that strange for a comic book story, especially when you consider the origin of one of Marvels most famous characters, the Punisher. But theres something in the way Mark Millar and Bryan Hitch go about murdering the wife and children of Clint Barton, aka, Hawkeye, in Ultimates 2 #7 that is incredibly unsettling and will likely never find its way into an Avengers movie, even if at some point Scarlett Johansson's Black Widow becomes a villain. In Ultimates 2, the team learns that someone has betrayed the group from the inside. The mastermind turns out to be Black Widow, who might have the best line of the entire series when she tells her shocked boyfriend Tony Stark that he shouldnt be surprised that his Russian spy girlfriend is the traitor. Prior to the Black Widow reveal, Millar and Hitch deliver an excruciating sequence where the reader sees one of Hawkeyes kids running in terror from the masked murderers who have entered the house and Clint's wife. As the child runs into his fathers arms, the main assassin (later revealed to be Black Widow) shoots the little one and murders him. Having such a graphic death of anyone let alone a child take place in Avengers: Age of Ultron would instantly give the movie a mature rating, a major no no for a studio hoping to break a billion dollars with its summer blockbuster. Besides, an actress as popular as ScarJo would never agree to portray a cold-blooded child killer in a comic book movie.
