^^^I think the technical term for Jesse is antivillain. What Walt wants and does is driving all the action and drama, so he is the protagonist, even if he is an antihero. Hank is the antagonist.
YES! & as an antagonist, Hank is fascinating, because he IS the one with the strongest moral center, but it's worn on him, & made him a serious asshole. The way he treated his wife during the recovery was brutal, & there's been no reconciling of that either
