I get how people are upset that Hank died and don't like Walt. However, I see it differently. Walt was good to Hank and Marie. If not for their financial help Hank may not have ever walked again, according to the doctors. He needed the best in physical therapy for a certain amount of time. Their insurance wouldn't cover it.
Plus, nothing was to be gained by going after Walt. He was out of the business and he is dying from cancer. AND Hank would end up getting into trouble for all the laws he violated. He enabled Walt to commit lots of crimes by his violation of his duty to the DEA. So, Hank would have gone down too, perhaps not to prison, but loss of his career and retirement. And Hank was too bullheaded to realize that he was going in over his head. He didn't get backup. He didn't follow protocol. He didn't get warrants. He ran rogue. He didn't have plan B. He underestimated Walt. Just like Jesse warned him. So, no. I don't have much compassion for Hank.
