I think it’s bc 1. Their boundaries don’t align so there are moral issues for the top and he outputs that by shaming him.
2. The bottom doesn’t always seem to understand the difference between play and abuse, just like what the ML is upset at him about. He thinks of it as a game (especially regarding the safe word). His blatant refusal to say it, even if he has to go in an ambulance, is a danger to himself. He doesn’t understand the rules of the play that they semi-established in the beginning of the story.
3. The ML is mainly worried about the MC and that plus his potential feelings are getting caught up together, resulting in this clinging on to their relationship.
Truly I think they both have issues in this situation, and rather than ML thinking he needs to “teach” and shame MC, they need to have a thorough discussion of their boundaries and what they want from each other. ML also needs to learn how to say the safe word as well, instead of putting it all on MC to end the play (mainly bc he clearly doesn’t have the capacity to). Actually thinking about it I don’t think he ever got one in the first place. They hardly discussed terms in the beginning as well iirc bc of MCs insistence to enter a play. Tsk
ML is just a bad dom overall. No control of the scene and it spirals every single time.
(Btw this post is agreeing with you, just trying to explain some of his reasonings)
honestly what did the MC do that was so bad????
like he was upfront and very clear about what he wanted from the beginning, which is heavy pain play and sadomasochism. the top *agreed* to it, fully knowing what the mc was asking for. he said he could provide it.
then he couldnt. MC complained again and again that the top wasn't giving him what he wanted, wasn't doing enough, and ML actively ignored him and even got annoyed/mad about MC not being satisfied.
like I'm sorry but the one who wasn't being clear and comunicative about his desires isn't the bottom, it's the top.
heavy play exists, and as long as there's safety measures like safe words and aftercare, consent and communication, there's really nothing wrong with it. the only thing wrong with them is the top, cause he's not into that.
and instead of just going "look, that's too much for me, I can't do that for you", he blamed the bottom for his preferences which is a really fucking shitty thing to do. there's nothing wrong with having kinks, you just gotta find someone who's also into them.
and then, when the MC figured that the top wasn't gonna be that for him, and tried breaking up w him and finding someone else who would, the top stopped him, and got mad at him for that too.
like, either give him what he wants *without* shaming/blaming/resenting the MC for that, of let him find someone else who will!
of course the top can feel bad about the situation, but that's the result of him going through with something he didn't want to do because he refused to let the bottom go. safewords exist for the doms too! he could've said no, the bottom already tried many times to stop what they had going on, to go find someone actually willing to give him what he wants, but the top actively stopped him! the fuck else was MC supposed to do???
idk idk idk like YES the bottom should've realised that the top was uncomfortable and stopped but guess what he TRIED!!! the top wouldn't let him leave!!!!
fucking asshole, don't make the fact that you went through, completely of your own free will and stubborness, with something you didn't want, everyone else's problem!
it just really irks me how much he shames the bottom for his tastes, when he was the first to tell him he was into that as well. he ain't got shit to be ashamed of
