How do you write a character with Stockholm syndrome, without just dumping a truckload of exposition?

I call her the titaness, mainly because she's massive and is augmented by robotic limbs. Not by her choice mind you.

Years back she was caught in between the consequences of a revolt. A revolt that took her father's life. To make matters worse, she had to watch the men who murdered him: parade the streets and call themselves the "Anvils of Justice".

Confronted by the worst conditions to plague Motazad, the paladins had grown aborted and scarred by light.

Within the deepest pit of the city, they found a little girl hiding from the burning world that shamed her so. Instead of stumbling on their humanity, she only found hate within their gaze. Her world was such that cockroaches had higher life expectancy. She knew she would die that day.

Fortunately for her, one of the elders found her still alive by some miracle. Her state suggested otherwise. The man quickly saved her in a series of steps that took months. She was conscious for some of the moments. Having no one else to talk to, she eventually developed a strong relationship with the man who saved her.

However, she discovers that the man is actually one of the leaders of the sect that reduced her ancestry to ash. She's conflicted because she's developed a strong relationship with the man.

My problem now, I can make her compromise on the matter but how do I make her feel the same way towards the whole organisation, including the very people who nearly killed her. Not only that but to such an extent that she will kill for the organisation?
