Is black window a villain

Black Widow, also known as Natasha Romanoff, is primarily portrayed as a hero in the Marvel Cinematic Universe and comic books. Initially introduced as an antagonist in "Iron Man 2," she evolves into a key member of the Avengers and a complex character with a tragic backstory. While she has a morally ambiguous past as a spy and assassin, her character ultimately seeks redemption and fights for the greater good. Thus, while she has villainous traits, she is not considered a villain in her overall narrative arc.
