But he didn't foil their attempts to join the Sorority. Rachel was never going to let the 5 of them in. She knew Kate and crew were too powerful so she was always planning to break them up. That wasn't the MCs doing. What was the MCs doing was painting a bigger target on their back and causing the entire Sorority's images leaked and the sorority itself disbanded. Then Rachel got expelled and her life ruined. The biggest success he has had was in hurting the woobie of the group, and Charlotte if he went down that route. Only one of which offered any real catharsis.
I think I will leave this as a difference of opinion. That fact that Kate could turn defeat into victory was not the MC's doing. They were defeated fair and square and they themselves acknowledged it after not all being accepted into the Sorority. It was short-lived.
And if the girls are supposed to be canon fodder for Kate, we should see more of it than we currently do. We have the advantage the MC doesn't in that we can see what the BS do when they are by themselves, and Kate and crew are nothing but supportive of each other. It's the reason I don't think Kate is the main villain in the piece. Now, if say we had evidence that she did in fact leak the images of the MC in high school and set up his social ostracization in order to say, separate Annie from her only real support structure outside the group, then that would be something. If we saw her pushing the BS into doing things they very much didn't want to do, or making it about personal loyalty to HER, I might agree with you. But we have had the ability to see Kate away from the act she has to put on for the MC, and everything we see is at worst someone who is overly ambitious and someone who will go out of her way to get back at anyone who hurts the group. An overprotective den mother.
The BS have different methods of bullying:
Emma:
The photo was leaked by Emma, it served no bigger purpose. It was just Emma being mischievous.
Emma is the type of person that just does stuff without thinking on how it affects other people.
The type that would laugh if someone trips and falls, without feeling bad for the person etc. etc.
She by her very nature lacks any empathy, apart from her own friends and people close to her.
Charlotte:
Charlotte is he typical bully. I would venture a guess to say that most of the direct bullying were done by her. Maybe even most of the derived bullying, since she was not afraid to use her body. The reason for her bullying seems to be her own insecurities plus maybe a suppressed empathy for other people. She is also bitter and is maybe a bit angry at the world and want other people to suffer like she was suffering.
Annie and Sarah:
I think they were mostly enablers. Not ever speaking up about anything. I think they both lied to themselves and keep lying to themselves to tell them that nothing really bad happened. I think of the two, Annie has a bit more of a ruthless streak, that can get nasty if she was hurt by something/someone. I think Sarah cannot hurt a fly on her own, but once again, she will do anything for her friends, including doing her part when asked.
Kate:
Kate likes power. That is undisputed. I think she has a warped view on how to achieve power. She will tolerate injustices and bullying if at means she gets more power. I don't think she initiates most of the bullying at school or most of it were at her behest. (I think most of it were done and directed by Emma and Charlotte). But it played into her hand of achieving more power at school, so she allowed it. No I do not think she has some kind of a masterplan. She achieves power and then tries to wield her power for what she sees as a "good cause" since that probably makes her feel accomplished.
But power comes before anything else. She knows that the way to achieve things is through power alone and that is always her primary goal. Forming the BS was always part of her way to achieve power, but that does not mean that she does not care for them. I think she genuinely loves and care for her squad.
Is Kate evil? No I don't think so. I think she is still young enough to be corrected and can achieve great things, without stepping on anyone else. It's just her frame of reference was her dad: Not the best influencer by far. Ath this stage, she is definitely not a good person.
In my playthrough, I'm hoping to achieve that. But the MC would need to totally break her down to achieve that. Not sure if that is possible.
