Spirit + Human = Abomination
According to the Chantry. The majority of mages believe the Chantry and the Chantry influences what can and can't be taught at the circles.

Sometimes it appears that abominations are just mindless hulking brutes with large tumors covering their bodies. They sometimes talk and show a form of thinking, other times they're slight animals destroying everything they come across.
Correct. Different abominations have different levels of intelligence, power, and control over their state.
Think about it this way: Does a 2-year-old and a 30-year-old act in the same way? There's a huge difference between a rage or hunger spirit entering the mortal world for the first time, and a desire spirit that has over a century's experience in the bodies of various people.

Sometimes the Abomination isn't an Abomination, like Uldred, instead they turn into a Demon.
Sometimes the abomination is more of a possession, like Wynne, Connor, and Anders. This form of Abomination seems to 'merge' with the personality of the person (except for Wynne who seems the same without any difference with Faith).
Then there's the Duchess an Abomination who according to Justice has now become a demon, is that the explaination for Uldred? The Duchess had decades in the Fade using and feeding off of spirits/souls to become that. How did Uldred become a demon so quickly?
Powerful demon + Powerful mage = Abomination that can turn into a 'demon.'
But I don't believe what Justice said was right. According to Justice, he doesn't really understand what a demon is other than he doesn't like it. Then there's his behavior in DA 2.
And then there's the special case of Connor's possession, which is cured by killing the Desire Demon that possessed him. This can't be too special of a case since Irving, Jowen, and Morrigan all seem to know that you can go into the Fade and kill a demon and the possessed mage will revert to normal
Morrigan is a blood mage raised by Flemith and Irving is the first Enchanter. I don't think Jowen should have known that, but I assume he was given special knowledge because the PC can enter the castle without Morrigan.
According to the writers, it's little-known and no one has managed to successfully undo a possession that anyone knows of.
Even more interesting is the fact that possessed mages like Anders and Connor have moments without the demon/spirit controlling them.
According to lore, the Fade and Mortal realm are actually one. The Veil is actually a mode of perception.
I'd suggest you think of the Fade as the emotional/conceptual realm. The chair you're sitting on is a physical object, but you also have the idea of a chair, and if you walk into the other room you have the memory of a chair. And while you can't see the chair I'm sitting on right now and have never seen it, you have the concept of 'chair' and can probably furnish a mental image.
Your concept of a chair exists along with the physical object, even if the physical object never interacts with that concept. Now imagine that your concept of a chair had a sense of identity. We could call that a 'chair spirit.' Imagine if that chair spirit wanted to enter the real world and see what was up with all those imaginary butts that's been sitting on it?
You know what? I have no idea where this is going. What was the question?
