2. Hank Schrader
Ever since the halfway point of season 5, Breaking Bad has been steadily building up to one dramatic face-off between Walt and his brother-in-law DEA agent Hank. It's quite clear that these two heavyweights are going to square up to each other before all is said and done, which creates a number of possibilities. One of them is Hank catching "Heisenberg" and sending him to prison, but this would be far too anti-climactic and this feud can only end with any modicum of satisfaction if one - or both - of them die. Hank was one of the show's more likable characters up until season 5 with viewers rooting for him, especially during his confrontation with Tuco Salamanca and later "The Cousins". However, ever since he found out about Walt's secret life, Hank has taken on a darker persona and will seemingly stop at nothing until justice is served in his eyes. This has made the once-likable DEA agent villainous in the perceptions of those rooting for Walter White, seemingly making him something of an "anti-hero" - an anti-hero who is probably going to die if Walter lives to the last.
