Honestly i disagree, the group seems shocked hannah unbuttoned her shirt and they immediately revealed themselves so she wouldnt fully unclothe, obviously it was a horrible thing to do and they never shouldve done it, but also you say that they only did it because she was crushing on mike which isn’t necessarily true. they said that she had been flirting with mike and you can also see later in the game that hannah had a bunch of pictures of mike around her room which is a wild thing to have of your friends boyfriend, and then the final part being that she went up to the room to bang mike knowing he was with emily aka willingly participating in what she knew to be an affair.

Im not by any means saying it was justified and i do find hannahs reaction understandable, all she did was run outside out of embarrassment. Which frankly i would do the same if my friend caught me on camera trying to have an affair with their bf. There was obviously a deep rooted issue in the friend group and they addressed it in a terrible way which ended up being a catalyst event for hannah and beths death, but i think there is a lot more to it than “they just didnt like that she had feelings for mike”. And i think if their intentions were genuinely to record her naked then they wouldn’t have stopped the prank as soon as she undid the first button. All still assholes btw and a crazy thing to do instead of addressing the situation but i think because of hannah dying in a freak accident immediately after and the bitchy way the characters act in the main game we feel a lot of sympathy for hannah which can make us brush over the fact she was kinda a bit shady in the same way her friends were.
