According to the rules, Dyon was in fact in the wrong. So, he didn't find any issues with an elder being angry with him. He just didn't care.
Just a few days ago, dozens of elders watched Donari kill an inner disciple and no one made a move on him. Dyon wouldn't wantonly kill people, in fact, he wasn't even serious about killing that inner disciple who brought him his robes, but that didn't mean he would allow slaps to his face in the name of following the rules.
This said, Dyon still needed Unseen Peak. There was a reason he hadn't just used the same overbearing tactic to force his way in Soul Rending Peak, and that was because the elders of that main peak couldn't be so easily dealt with by Dyon even in his unsuppressed state, let alone his suppressed one. As such, he was forced to take advantage of Unseen Peak. In the end, this meant that Dyon's rule breaking actions still had to maintain an air of rationality, lest he lose his foothold into Soul Rending Peak.
