Hulrun is overcritisized

First of all Yes I do think his decisions are morally questionable. But their are a few things in his favor
One Liotr Hawkblade is one of his diciples and seems to think that Hulrun would approve of his actions implying that perhaps Hulrun is usually more reasonable than we see on screen.

Second. The desnan adepts are INCREDIBLY suspect. and they DID tresspass in a sensitive area. Sure we with our metaknowledge know that they in fact were in the right. But Hulrun does not.

Speaking of metaknowledge. It turns out the Desnans were taking orders from a mysterious voice. One which for all they know could have been a demon. As a matter of fact it was one. Specificallly arushalae.

Hulrun has a problem with Arushalae but is willing to take your word for it that she's ok.

Hulrun can in fact listen to reason. You just have to pass a persuasion check.

Now for the less good thing. He burned ember. I read somewhere this had something to do with her family sheltering cultists? I'm not actually sure what happened so I can't really accuse or defend him.
