I thought Flag-Smasher was fine villain but the show kept trying to say that she wasn't a villain when she obviously was. I think they should have written her more like Killmonger a man who starts off having a noble goal but whose actions turn him into a monster. Both Erik and Karli have very similar plots which is get revenge on the people who wronged them by making them go through the same thing; Killmonger wanted to Black people and to use vibranium weapons to threaten and oppress White people and Flag-Smasher wanted those who survived the Blip to have a more secure lifestyle and social status than those who died. The difference is that Erik knows full well that he is a terrorist revolutionary but believes that his ends justify his means whereas Karli and even Captain America himself refuses to accept that while she might have a legit grievance with the GRC, blowing up innocent people for the sake of a message in the definition of terrorist, TLDR if they wanted the villain to be morally grey they should have let U.S. Agent be the main threat
