A flawed person can still make good work. Yes, often their character does seep into their work whether they intend it to or not, but I can think of several good works which have dubious creators. I've laughed at Yugioh Abridged since I was in high school, and my wife and I still quote it around the house. I don't think the failings of the creator should matter much to the people who he has entertained over the years.
