Detailed Explanation
Walter White's body count grows throughout the series as he transforms from a desperate cancer patient to the ruthless drug lord Heisenberg. His direct kills include: Emilio Koyama (phosphine gas), Krazy-8 (strangled with a bike lock), two rival drug dealers (ran over with his car, shot), Gustavo Fring (pipe bomb via Hector), Mike Ehrmantraut (shot in anger), and Jack Welker's entire neo-Nazi gang (rigged M60 machine gun). He's indirectly responsible for the Wayfarer 515 plane crash (167 deaths) through his actions with Jane, and he poisoned Brock Cantillo (survived). His total death toll exceeds 200 when including indirect deaths.
