I wouldn't say "Sasuke became unlikable"... for me he was unlikeable from the very starts. I might have sypathised with him in the beginning for his loss, but the way he chose to deal with it never made any sense to me from beginning to end. No real person would ever behave as stupid and inconsistant as him.

With Hakuryuu on the other hand I can still sympathise, even after what he did and his actions do make sense. Even without falling into depravity and the acompanying changes in personality, some real people might have done the same thing as him.

Though I agree with Gisme that the respective mangaka try to make Hakuryuu and Sasuke fill the same roll. It's just that Kishi failed really badly at making Sasuke relatable and realistic, while Shinobu Ohtaka succeded.
