Once you had finished Wizard and Glass, did your feelings about The Gunslinger change?

I think that it is clear that Stephen King meant to make the character of Roland more sympathetic with this story. If anyone disagrees, feel free to say so, and please let us know what your own outlook on the character was. However, what I am primarily asking about is how many of us who do believe that this was the author’s intention was he successful with. Did you get more understanding of the gunslinger’s beliefs and behavior?

If not, then do you think it's conceivable that learning more about the still missing chapters of his past (e.g. from comics or from more revising of novels) could clarify remaining questions, or are some of you of the opinion that his attitude and the decisions which he made early in the story will never make much sense?
