Two Big Differences Between Mythal And Solas Is That Solas Regrets All The Terrible Things He's Done.

Two big differences between Mythal and Solas is that Solas regrets all the terrible things he's done. That is, in fact, a major plot point and theme. He shows remorse and at his core he wants to fix his mistakes. Mythal, or at least the fragment you can speak to, doesn't regret her actions at all. If you call her on the blight being her fault she attacks you. She doesn't accept responsibility. Solas does. That doesn't erase the guilt or culpability, but it does make me respect him more than I do her.

The second difference is that Solas rejects the notion that he's a god. Mythal doesn't. Again, if you ask her to help you against the other Evanuris and state that the people don't need gods she gets angry and attacks you. Maybe it's just the anarchist in me, but I've got a lot more respect for someone who rejects worship and fights tyranny than I do the tyrant being fought. Because that is what she was, as much as any of the others. A benevolent dictator and slave owner is still a dictator and a slave owner.

Now, if I'm putting my character analysis hat on for Mythal *specifically* I'd say that it's possible she reacts like this because she does feel guilt. I know, that does contradict what I just said. But I do think it's possible that her anger and violent reaction is a defense mechanism and a shield against being confronted with the truth of the damage she caused. Admitting that you're wrong is one of the hardest things a person can do, even without having had centuries of worship heaped on you and going to your head. So when someone you see as lesser calls you out to your face? That's a hard pill to swallow. Again though. Solas does swallow it. Solas takes blame. Heaps it upon himself until it defines everything he does (which is another problem in itself but We Don't Have Time For That Right Now). Mythal, by contrast, rejects it. Right until she absolves Solas of his duty, and finally takes some responsibility herself.
