6. The Death of Jane
The people that Walt killed up until this point didnt mean a lot to anyone in his life, they were drug dealers and hardened criminals. The death of Jane is different, she meant a lot to Jesse, Walts business partner and surrogate son which makes Walts actions all the more selfish and shocking. Even though Walt doesnt kill Jane he does facilitate her death by not rolling her onto her side when she starts to throw up, leaving her to choke on her own vomit. Like with the death of Crazy 8 it is clear that Walts soul is damaged by this act, he feels great remorse for her death (as revealed cryptically in the season three episode Fly) even if he might have been able to rationalise for it at the time. The most evil thing about this act though is how he lets Jesse take the blame, he lets Jesse handle the guilt which tortures him and leads him further into his own personal darkness.
