Maul isn't a Mandalorian. The entire plot of this arc was Maul looking for fools to exploit to build a power base for his own goals. He tried that with pirates. He failed. He succeeded with Mandalorians, because their "code" was a weakness that allowed him to exploit them. He did not actually care about it in a meaningful way. He said it explicitly. His only goal was to exploit them as muscle for his personal motives that didn't factor Mandalore and its people anywhere in them. They were tools, expendable pawns.

His goal was establishing Underworld Empire, and Death Watch were to be reduced to yet another criminal scum next to Black Sun, Pykes and the Hutts. Even though they are villains, Death Watch were above that. They had actual ideology of their own beyond money, they had pride and identity. Vizsla and Bo wanted strong but INDEPENDENT Mandalore, and they wanted to decide their own goals and future, they wanted to fight their OWN wars and do the things their way, and not be pawns of a Sith, whose interests have nothing in common with theirs.

Vizsla and Bo knew that, and they were actively aware of it, and explicitly said that they can't trust Maul, but they needed him to get Mandalore back, and they need to kill him immediately once it is done. They were arrogant to think they could use him and get away with it. Maul outmaneuvered them by exploiting their dogmatic adherence to their "tradition" and used it against them, which was their downfall. He publicly challenged Vizsla in front of his men, questioning not only his authority but his loyalty to their traditions, his honor as a warrior. Vizsla had no choice but to accept it, or he'd lose everything. If Vizsla was smart like Hondo, he'd just put a bullet in Maul's head when he had the chance. Bo Katan was willing to betray her ideals, her reputation, her brothers in arms, but it was absolutely the right thing to do. And she was right: when their usefulness came to an end, Maul just abandoned them.
