It's simple. Taking them down is the only thing I have to look forward to after what they've done. It's quite literally why I'm still reading. So I have to believe that we'll be able to triumph, save the abused and oppressed, and have some semblance of a happy ending.
Otherwise what everyone has had to endure is pointless.
At least if you can't take control of the club it would be good to be able to help all the carnations, Veronica's problem would be as simple as changing her business model to a more profitable approach, Felicia would not need someone to accept her as a member of the Club and Rosalind would literally be solved with money, it is so simple that Felicia gives Roselind money to help her win the game and both come out winning with this Felicia wins the game and we help the other two, problem solved.
I'm thinking that the mc will be able to turn Chuck and August against Kat once whatever she's plotting comes to light. I'm not sure about Chuck and August. August seems like as long as his daughter is happy he'd be happy stepping back and letting her run the buisness. I think Chuck would gift his shares to the mc if Ian hasn't gotten his act together. I think they could reform the club. I have a harder time thinking of a reason of how/why to really take down A/C. I can't really think of any leverage because it seems Chuck has the cops in his pockets. Unless he steps down to protect his family that would fit. August may also have to worry about his gang but Chuck's cop connections and profitable club seems to make them a non factor. Unless they go after Hana to get to him.
You could also have another more pacifist route so to speak, since all the members have an age to retire and leave the club to a new generation, Hana would have her share through inheritance from Agust and Ian from Uncle Chuck, and since Kathleen is so determined to have Edwin as her apprentice perhaps she would give him her position in the club, with that the 3 of them could manage the club in a less shady way, you know without making employees disappear or irresponsibly neglecting the health of their "employees".
And as for the pale carnation game, I've been thinking that it wouldn't be so bad if at the end you could help the finalists, so that the contest would continue as we all know and if you got to the end without withdrawing, you would fulfill the reward promised to the participants behind the scenes, of course this will be something that they will only know when the game ends so the tension of losing will still be there and they will only get their reward if they haven't withdrawn.
The tests will continue to be tough and will put the participants to the limit, but if they make it to the end it will be worth it.
