^This, I think this is the most important part here.
Static characters have emotion, they are still people, they just maintain the same beliefs and goals throughout.
It reminds me of my favorite character in visual medium, Technoblade from Dream SMP
Technoblade is a static character, he has one set of goals and he's willing to do anything to get them. However his line "I'm a person!" has more emotional weight than many of the Dynamic characters entire arcs, preciely for that reason. Because he doesn't change, becuase he follows one path the other characters dehumanise him, treat him more like a force of nature, an event than a person. So when he says "I'm a person!" it's a reminder that even though he doesn't show it, even though it doesn't change him, he stil hurts.
