Indeed, but she doesn't learn. She also doesn't accept any view unless is correlates with hers.
Now, my mage hated being a prisoner in the tower, always watched, leashed by her blood. She never had a choice, once her magic became obvious, she was imprisoned, hated and feared by the chantry and the templars. She had no easy life, at least Morrigan had glimpses of freedom.
My mage also knows that many if not most of the other mages also feel constricted and imprisoned as well as mistreated. They were her only companions through childhood and adolesence, she will definitely not further their doom in any way, shape or form.
Jowan's story more or less confirmed this, just ask him about his family. Poor guy, what a bummer. And then the only prospect for him is to become a robot, or dead. Yes, he's a blood mage, but my PC doesn't know that until the end of his and Lily's quest.
Aside from that, in my opinion, using a mage's phylactery against her/him is blood magic. That's debatable and depends on a personal pov, but I think it is.
My mage knows far better than Morrigan what's going on, so her experiences are to be taken into account. Morrigan could've easily ended up in the circle as well, and I would like to see her start a revolt. The mages in the tower, with all their powers of magic still would get their butts handed to them.
It is said that the First Enchanter governs the mages, but I wouldn't like to see what would happen to him/her and all the mages if they tried to push something through that doesn't meet Chantry/Templar approval. That Rite of Annulment would be there in no time. So in my opinion, Morrigan is all wet, and shows great immaturity in regards to the circle.
