This probably wouldn’t work well, though. Most masochists in ‘healthy’ situations don’t endure constant, daily physical torture that could include broken bones, removed digits, malnourishment, or unhealthy lengths in solitary confinement. And there is usually a ‘build up’ and ‘let down’ in a *mutually agreed to* experience along with words or gestures to slow down or halt the situation if things go too far. So unless they worked out terms of the experience in advance and the torturer agreed to ease up after hearing a safe word, I don’t think this will be too effective. (I heard all of this from a friend.)
Then just take all the masochist spy people, use fancy spy things to make them even deeper down the masochist rabbit hole to the point of no amount of torture being too much and then send them out and get all the gains.
Considering AoT is anime, the writers can do whatever they want. In real life, however, I am now grossly disturbed and totally put off based on your insensitive comment by the thought of what you might do if you were ever in a position of power. Or maybe... I’m intrigued.
Masochism is less about pleasure from pain and more about pleasure from the situation delivered via pain. A masochist isn't going to be orgasming over a broken bone.
Masochism is an umbrella term, though algolagnia isn't. It's a sickness that transforms all kinds of physical pain into sexual arousal. There's more about algolagnia here: https://en.m.wikipedia.org/wiki/Algolagnia
And also a comic with a character that has that sickness, though I have to warn you, it's VERY nsfw: https://tapas.io/episode/467811
this all sounds good but masochist is about pain/pleasure for a short time. torture isn't about pain it's about mentally breaking some one down. lack of sleep lack of food physical discomfort and fear. come in and hit some one with a baseball bat breaks their arm but true torture is giving them a clock to watch and telling them your going to break a finger every hour. imagine that last 5 minutes before the torturer comes in to break the next finger.

I'm sorry. I'm so sorry
