Walter White isn't the only cancer victim to break bad. When Tobin Bell's John Kramer is diagnosed with an inoperable tumour, he attempts to take his own life, but fails. In that moment, he becomes his very own Heisenberg as The Jigsaw Killer, a twisted genius who traps his victims in elaborate scenarios designed to make them appreciate the fact that they're alive - if they survive, of course. Kramer's curious moral code (look back at the films and you could even argue that he never directly kills anyone; his victims all contribute to their own downfall) makes him, by some distance, the most interesting screen monster since Freddy Krueger. It's a shame that Bell was relegated to flashback work for the last few instalments.
