It's really hard for me to explain. Because it's not that it was a fight scene. I enjoy fight scenes. I love writing them, for example. They're full of energy and exciting. The adrenaline rush and... I mean, in Luke Cage, the Bring Da Ruckus scene? Fuck yes, love that scene.
It's because it's not a fight scene. It's a murder scene.
The difference between a fight and a murder is subtle. A fight is where there is a contest between relative equals. A murder occurs when a victim has no real chance.
This scene made my partner uncomfortable (she's a rape survivor). For her, she suffered disquiet because she knows how it feels to be powerless to stop something.
For me, I think that's the distinction you're looking for.
