I think the general public in the series views him as a bad guy. When he started cooking his only intentions was to help his family (not really, he revealed last episode that he did it because "it is fun") and because he did this he really pushed his relationshiop with everyone else out of the picture. So his family (skylar) did view him as a good man near the end of season five and the early season six although at the end, everyone really did hate him, so i would say that he is viewed as a bad guy, but we all know that he was good.
