I want to point out a line spoken by Ayo in episode 4:
No one seems to have even blinked an eye at this, while if anyone else in the show had said this about themselves or their organization, there would be a big uproar. Imagine if Walker had said that about himself or the GRC. I think this also ties into the overall theme of bias and racism that has happened so far. Some Wakandans do tend to look down on the rest of the world, and the other races, and think themselves superior. This kind of disrespect for the outside world and the laws that are not their own makes them just a mirror image of other supremacist groups. The only thing they may not have in common is the hate. And you can bet that if Ayo kills Zemo in a fight, or murders him as he is trying to surrender again, that she would never let herself be arrested by the local authorities.
