Um im feeling very wrong about this?

So apparently I had this good af friend group. Like not irl, an online friend grp, but since we all lived kind of close too each other, it didn't feel that our friendship was only online based. And the fact it was queen grp too. Since all of them were gay or lesbian or Trans. Everything was going good or so I thought... like one of my gay friend from the same grp, let's name him P, had a bf, amd their dating life was going good, until bf started ghosting and making excuses to meet up with P. So P told us about it. Since the bf was also mutual to one of the friend of our friend grp, let's call him A, so P asked A to take his side because he was feeling wronged about this and A always had this view that ppl should be given 2nd chances, and so he told P. P was angry but let it go thinking, he should do what feels rather than asking others and siding eith him, probably because everyone, including me were with him on the break up. A later said P to take care and that was it. A month or two later, e got to that P's bf was a minor groomer and he was grooming a distant relative of one of our youngest friend in the grp. They told us about it and we immediately blocked our contacts with the bf too. A said that he wanted to know if this is true or not, when the youngest showed proof, he was like okay, I see, I'll block him too.
Months later, P comes to me and says 'A keeps on irritating me. He never took myside when I and my ex broke off and kept on being neutral because according to him it is okay for cheaters to have a second chance!' I went liek girl, okay yeah that is bad if you know the truth about someone. Now P and A have arguments on every single thing, they can find on to argue, with P mostly giving up on this in the end, always. So in P's eyes, A was bullying him and P hold onto resentment during the breakup period of his. He never liked how A always poked at him and made fun of things.
Things to note, A never liked digital artists, because to him, it is just pixels amd so ppl should not hate ai art either, because both are pixels and ppl should turn to traditional because that's more authentic and natural. That were his views and, he got into a lot of fights with me for this same topic, because as an artist and a digital artist to top it off, his opinions on this always annoyed me. So P amd I became close this way. Always talking about how is A annoying amd how he is bitchy and stuff. Basically back btiching him. P and I either talked about A or our bad life or how P had love life or how im struggling with my college life.
Recently like a week ago, the youngest friend, who is also an artist, found out that she had an ai art with her, and thought that the official art was ai made, and put it in the grp. A being the guy who doesn't understands how dangerous ai is for artists and other jobs, kept poking the youngest how it is stupid to think a pixel will do something bad, for which even I jumped in the fight and called him out for hypocrisy on every point. Assumed things about his family and stuffs happened (i did apologizedhim for it). The youngest getting tired of this bs, called on to P and P hopped and also said lots to A. A felt bad, because to him, P was his closest friend out of all of us, whom he respected and admired and feeling betrayed about this left the grp. P feeling bad about this called onto emergency meeting where we discussed about what actually happened. Youngest amd I explained P everything and again started back bitching about A. A day later, P talked to A amd apologized for what he said I'm the grp chats to him, and asked him to give this argument a proper closure by apologising to our youngest. Amd so he did, but to P it wasn't enough because, the apology wasn't enough emotional, and felt bland. A didn't understood this. P and I were having fun poking A by doing this. So A decided to go into dm of the youngest to let them know the whole picture and that he understood what they meant. The youngest told P about it and P got annoyed saying this person doesn't knows how to stop things, he keeps on pushing onto one subject always, and stuffs. P was getting annoyed by A more and more always. So I said 'Let him yk you are getting annoyed by this and put a stop because it is not worth our energy.' And so he did. A said okay and moved on.
Now P one day told me 'I really really hate A so much it is boiling my blood.' It was a random day so I was like okay, text him that and move on. P texted him and he told me, 'im blocking him so be the mediator between us.' I went 'okayyyyy'.
Now comesour oldest friend, K. This person, technically the oldest and by far having the most worst out of all us. Pretty bad. Her lover cheated on her, blamed her for having everything and like ppl hated her. I'm really close with her and I always defend her in everything, including fighting on her behalf everywhere. She always looked after me, and give me advices, helped me in studies. So for me, to defend her felt everything. So I fought with her bf on a dc server, bought her back from exile because she cut off everyone and everything. Lotso f thing happened and I was worried so I gave up on my sleep to get into contact with her. After 2 days of hard work I got into contact and explained her, told her it is okay and I understand if she doesn't wamts to come back. That same evening she came back. She semd me a msg, which had her chat with A asking for some opinion. I told her to say him why you did this and that (it was clinical, can't get too specific) and there we go. Later K put on the same msges into the grp that was made only for gossips between me, P, youngest amd K. She was ranting out how A is so dumb and hos he cam claim to be a 4th Yr medical student if he doesn't knows this amd that basic stuff. To which I agreed because it was truly basic and common knowledge. Now the issue was that grp which was for fruity daily life gossips turned into a back bitching grp for A. And P was the one back bitching . With K also removing her frustration. And P used me again as a mediator to send A msges. And it was always degrading A. Even when A was apologising for not taking P's side during breakup or annoying him. He did everything. And today it went far. P sent me a reel, and told me to sent it to A. I thought it must be something and did not watched it for privacy reasons. I felt so bad for it because it called A a lonely ass bitch toxic bitch and whatnot. A always thought of P as his closest friend, probably yes he did hurt him and me too, but it was nothing, so why semd that. And K was taking P's side too. Also idk but today out of nowhere P declared himself straight and im now feeling very weird amd awfully awkward and am getting thjs creepy feeling, which usually comes out true, so I tried telling to K, but she didn't understood it, and I couldn't tell A because to him I'm sad amd spending my days here (which is true, I'm. I completed lots of bl mangas amd manhwas, caught up with marinating yaois, yeah, im using this as escape )
Anyways yeah I'm feeling bad, and I did apologised to A, not fully, like not with the details but yes I feel sorry and I said him, but other two are taking it far and Idk what to do to stop them. Also why am I getting creepy vibes from P out of nowhere
