When Breaking Bad started, Walt got into the meth-cooking biz as a way of keeping his family safe and secure after he wasn’t alive anymore, actions that led to his anti-hero labeling.
For Anna Gunn, the confusion came from how fans continued to hold Walt in such high regard in later seasons, despite how he’d become a deadly criminal whose ego drove him far deeper into the criminal underworld than he’d originally intended to go.
And yet Skyler would get thrown to the wolves essentially for also trying to keep the family members alive and safe, just because she served as an obstacle in Walt’s ascent/descent to Heisenbergian infamy.
