There are bad betrayals and good betrayals in 2 Kings. The bad betrayals involve the various conspiracies that bring down different kings. For example, when Hazael smothers the sick king Ben-Hadad of Aram with a wet piece of cloth, we can safely say that that's, well, pretty low. But God commands Jehu to essentially betray Joram and kill Jezebel and Ahab's whole family. It would normally be an act of treason, but instead God makes it good, sanctioning it. The same is true when Jehoiada orders Athaliah's death. She got into power by slaughtering her own family members (not good), hence committing treason against her is really the right thing to do.
