Were canonically obeying their Queen.
A guy Sylvanas had killed.
A council Sylvanas had killed.
A guy who killed her, and then she killed.
Are you not seeing the revolving pattern?
Every forsaken story is thoroughly employed with and revolves around Sylvanas. Zelling is the closest one to not being that way, but Lilian is employed against her will by Sylvanas so I’m sure that’s going to come up if Sylvanas doesn’t kill Zelling’s family for “holding onto the past” which is illegal in Forsaken culture atm.
Koltira is not Forsaken.
So, as we can see, she does not.
Dude she mass murdered the night elves because a night elf gave her some clap back. Then she mass murdered, mass damned, and mass enslaved the Horde. Then she continued intentionally and willfully killing the planet after being told that mining Azerite is killing the planet.
What more do you want?
