Ever wondered how a Timberwolf thinks? What goes through it's mind, is it intelligent, wise, in control, mad, feral, instinctual?
What if it's a bit of everything, I mean when the only thing that can really end you is fire or losing all potential material to regrow your body over and over and over, well I guess you could go from sane to mad to feral eventually. Especially since you effectively run on wild magic, well I guess losing that would end you too.

The only question is did they start that way? Or once, long ago, were they and thier kind something more. Something that has long since been forgotten, and what if one day far from then and closer to now something changed. What if they could get it all back? Would one be able to grasp it at all, and how would the world react to savage beasts revealing what they were once, and who made them change.
