Actually I should thank you for answering my question, I think you are right, if Cole doesn't remove people's memories (except of himself), what he does is different than what Justinia is talking about. I had a problem with the analogy of the body healing itself though, because we are talking about minds and they are not supposed to work the same way, but perhaps if we think that what Cole does is some sort of accelerated therapy and that he heal the minds by helping the people to understand the reasons of their suffering, the process seems more constructive in my opinion since he doesn't deprive the person he wishes to help from the key of his/her healing, this person still remember that (s)he suffered but also remember why (s)he feels better now.
Minds don't heal themselves? I wouldn't agree with that. Most people don't need therapy to work through their problems, they learn coping strategies on their own or from parents and role models.
I do think a lot of people mis-hear/ misunderstand what Cole says about "forgetting." The writer even clarified that when he says he's forgotten the real Cole (on the spirit path), what he really means is that he's let it go. He doesn't fixate on it. Not that he actually can't remember the person and events.
Example- my grandma has dementia, and sadly she will seize on certain events or impressions she gets and fixates on them, turning them over and over in her head. It makes her terribly fearful, and resentful because she'll take an imagined slight and chew on it over and over and over again. I really wish she had a Cole who could loosen her hold on some of those painful, destructive things so that they aren't as huge in her mind and other things can occupy her.
Of all the Characters Cole is the most ... wrong in my opinion. He just feels tacked on at the end of Haven and is very dis-likable, i've not once added him to my party and feel if he disappeared (pun intended) it would make zero difference..
Hes (to me) incredibly ugly, for me his face bugs out in my game (goes all pointed and freaky) I don't get how anyone can like this guy/thing all he ever likes is murder and tries to pass it off as hes helping people...
Here is my bugged Cole (which sums up my opinion on this terrible Character)
Well, thanks for sharing, but since Cole was a character in the novel Asunder he's not only not "tacked on," he's been in works probably longer than other companions. He's also vying with Flemeth, Loghain and Solas for my spot as most interesting character in Dragon Age.
You don't get how we could like a character that gives us insight into the motivations and hidden inner lives of companions and quest NPCs, and who up-ends the conventional understanding of spirits and the Fade? I guess you play the game for much different reasons than I do, then.
