A character who has given in and become submissive feeling disgust at themself, shame at what they have become. They lost whatever fight they had within them, whatever strength they had.
They can’t try to fight back anymore, now that they’ve debased themself completely. It is far too easy for their captor to remind them of their place, to laugh in their face at any display of courage. They are small and weak and pathetic and both of them know it. There’s no use in fighting that image. Now that the mask has slipped, they can’t believe in their own strength anymore.
The humiliation pulls them deep, deep down into shame and self-loathing. They are not the person they always thought they were, the person they desperately wanted, needed to be.
Their self image is broken. All they can see in themself anymore is weakness - and it’s reflected in the way everyone else looks at them too, like they’re some broken, helpless thing. How can they ever try to be strong again when they can’t see any strength within themself?
