2. Nursing Home Explosion
"Gus is dead... We've got work to do" It is the end of season four and Walter has manipulated both Jesse Pinkman and handicapped, elderly gangster Tio Salamanca into assisting in the murder of kingpin Gus Fring. Once Walt learns from Jesse that Gus visits his old rival Tio in a nursing home, Walt convinces the ailing Salamanca to attach a bomb to his wheelchair. Tio, who can only communicate by ringing a bell in Morse Code, agrees to use the bomb to blow up himself and Gus during his next visit. Sure enough, when Gus comes a callin', Tio Salamanca rings the bell, triggering the bomb. The ensuing blast kills Tio, one of Gus' henchmen, and blows off half of Gus' face (killing him not so quickly). To be clear, this plan of Walt's included the guaranteed deaths of two people (Salamanca and Gus), caused the death of another man (Tyrus, Gus' goon), risked the lives of countless innocents in the nursing home and tied into Walt's lie to Jesse about poisoning his girlfriend's son Brock. With this act, Walt showed that in the grand scheme, pretty much anybody was expendable.
