First, Thank you for the reply, and your game and creation. What follows is just my opinion.
I can see why possibly some mc's would want to help Lin, Jin, Maria, Nia, Robot, etc on their quests... If this book wasn't this book. However:
On top of all the things you did to the girls in say the 'early days' of the hotel; to coercing the church girl into performing extremely public cum walks in front of her sister; to keeping the twin sisters as a bj alarm; to keeping the 4 elf sex slaves I own (Nia, Sylvie, Peni, Ann) kept locked in the shed on low quality food rations; to all the other brainwashing I do around the house and all of the crazy shit there is to do in the dungeon. I'd say there is a pretty huge gap between 'helping' some of the girls and destroying others.
Honestly I play for the later part of the game I mentioned, and I'm not really looking for my mc to have any redemption. I would way rather bro-down and have another contest with Cornwall with a new batch of his girls; or turn the bar into a breastaurant with exhibition and submission points to work for me; or kali create a startup company with more robot models and different attachments; or have the college open up a sorority in my hotel. The last thing I want to do is go on a long, futile, and counter-to-my-interests dailog quest to liberate any of the girls in the harem.
Whatever though, it's your game, you know the arcs and how long you want to continue to work on the game and all that. For me the game/vn as a whole is great 10/10; its just the last 2-3 updates I end up not reading and skipping long-winded content, which unlike the core game (<v11), doesn't have any payoff.
