eh i dont really think they would or they should. The game is built a lot on blood, gore, and self harm, so that mini game is a key part of the game. Its like reloading from a shooter. But yeah, its definitely off putting sometimes.
That would only make sense if the minigame had a way to prevent the self harm. While I would still run it, as it is now, it just a gratuitous extra. Being able to toggle it wouldn't diminish from the experience, as the spite model still showed the self harm well enough before, especially once you open the medical window
tbf you can tweak settings like loot chance already, I don't think an option to disable some of the darker stuff like self-harm would be too "cheaty." in terms of functionality, it certainly plays a part, but I think game remains entirely intact without. (in terms of the mood system, maybe adding an option to disable the whole system, or just adding severe debuffs in place of SH)
