I'm conflicted. I understand why Madison is the way she is because of the abuse and degradation she gets and it's my nature to look first if the person is redeemable(Is there a path to redemption through love and kindness despite her crazy ways?). I'm a compassionate and forgiving person. Keep in mind I haven't played this game for some time and my memory is terrible(could be I never chose the other paths as well), but I don't remember Jason being killed; all I can remember is him diddling Tanya and his mom and sister and them being corrupted and insatiable(by the way not a fan of sharing them with Jason I don't remember the ntr being optional either, but please enlighten me.
I hated her initially, but I have a bigger problem with Ella more than Madison at this point. Its highly hypocritical for both the MC and Ella to get angry at each other for cheating.....because they were both cheating on each other. However, the MC not only had to deal with his memories being wiped/manipulated, but he was also under the influence of demons/succubus along with those around him. Now I do have a theory that perhaps aside from the abuse and trauma that has affected Madison, she is also a victim of Lileeva or another succubus, but unlike the MC who feels guilt and remorse, never do we see Ella react in the same way.
The fact that she knows how incredibly inappropriate and dysfunctional the relationship she has with Madison is....while still calling the MC her boyfriend and fantasizing about their pending wedding and given birth to their children is utter nonsense. Regardless of how badly she feels for Madison, she has knowingly and consensually engaged in this incestual lesbian affair for several years now iirc. IMO, she is in love with the idea of being with the MC and a future they could have had together had she remained faithful or even once bothered to go visit him in the UK. Actions speak louder than words and she clearly has not come to terms with her true feelings/sexuality.
Just as an example, I played the Selina only path where the MC conspires with Madison to break up with Ella. Again, while the MC is not perfect himself, at least he has always had a measure of guilt/shame carrying on with his indiscretions while still desiring to be Ella. In this scene, Ella and Madison are both naked, sitting on a bed about to watch porn together and presumably fuck each other after, when Ella sees the MC having sex with Selina. She freaks out, crying in anguish until Madison comforts her and just like that...in less than 10 minutes, she has made up her mind she's now completely a lesbian and only needs Madison's pussy to make her happy right before fucking Madison.
I mean, while I don't expect Ella to discover a previously unknown cuckquean fetish after watching that, the irony of her watching porn with her mother, naked, to get warmed up before having sex with her for the 100000th time only to react the way she did was insane. This was the man she was planning to marry and have a family with, yet rather than vow to hear from him directly prior to making any rash decisions, she took less than 5 minutes after letting what she watched sink in before she was all too eager to give Madison exactly what she wanted to hear. I know a lot of this was done for the purposes of breaking up Ella and the MC, but the way it was handled was way too unrealistic and ridiculous.
Now......all that being said, I still would take them both, plus Lilith if there was a way to redeem Madison and even redeem Ella to a lesser extent so they would all accept being in one big polyamorous relationship/family. I really like and respect Lilith for at least trying to stand up to Madison...especially in spite of her own lust and desire in wanting to join their play time, she refused to give up her own virginity, and instead insists on saving it for her future husband, on top of seeing the dysfunctional relationship for what it really is. I just would have liked her to try and talk to Ella separately, outside the house to try and reach her about the poor choices she is making and just how monstrous their mother really is.
