It has nothing to do with the face. The game has choices. If you can't admit that, you're just being facetious.
As for comparisons, they're both Ferelden commoners. Hawke's story is just an immigrant story, rather than homeland patriot. It isn't going to be exact. I'm just talking about mentality. If you can't roleplay an intelligent or strong character, that's your own fault. You have the freedom to do so. The world just doesn't revolve around Hawke, no matter how awesome. That doesn't mean that depletes who they are, as people.
I'm not talking about game choices, I'm talking about Hawke's nonoptional actions and behaviour. Letting their family be dragged to and running around the most dangerous and dysfunctional city in Thedas on suicidal errands to scrape together a small fortune in order to go on another even more suicidal quest in the vague hope of earning a larger fortune all in order to bribe officals just because Hawke's mother isn't satisfied with living in a normal house anymore.
The whole theme of the game is to "take flight", but all Hawke does is allow other people to pressure him/her into incredibly stupid decisions. At least Loghain acts decisively and somewhat rationally given the information he has and doesn't second-guess himself. If Hawke had a shred of his initiative and resolve they would have muscled their way into position as Viscount at the end of the game's second act, poisoned Meredith to keep her out of the running a la Eamon and tried to get Kirkwall under control instead of doing the heroic equivalent of menial chores for five years and waiting for the system to collapse under the pressure of all the insanity going on.
And if they'd been sane then they would have just gone back home to Ferelden after the Blight or at least spent the money they earned on soap and furniture like a normal human being and gotten that Lowtown house in proper order instead of repeatedly going out to risk their life for their mother's desire to get back to her roots, getting their entire family killed, caught by authorities and/or pressed into military service in the process.
And then there is their weird, extreme and completely unpredictable statements, which are as canon as anything else.
I have a Hawke in mind at the moment that I think I'm going to enjoy playing, but pretending her to be of Loghain's calibre as a character is futile and will only lead to disappointment. And my eventual Inquisitor won't be one to waste his useful allies.
