But, when has Walt killed anyone who wasn't a danger to him or his family?
He's still a smart man.
"Two CEO's of Grey Matter were killed today by Walter White, alleged co-founder and meth kingpin."
What does that do for him? Grey Matter would still continue to exist. The money would still exist. Two people would be dead. Other lives would be ruined for no gain.
I think after seeing that interview, the only thing that went off in Walt's mind was that he was truly unappreciated in every way possible. Everything he's worked for to make up for his mistake of leaving Grey Matter was worthless. All the people he's killed was for nothing. Does he really want to kill more people for nothing?
No. He wants to kill Todd and co. He wants to kill Lydia. He wants to kill Jesse.
Fortunately, they all think he's gone for good....he has the element of surprise. I don't even know if he has a plan at this point, but I'm sure he's expecting to kill all the nazis, take the ricin, and die in a jail as a man who's saved his family from persecution and potentially being murdered.
Jesse I really have no idea. He's already dead in so many other ways, it'll be something to see if he gets popped or suffers somewhere else. My guess is he dies a quick death....he's suffered long enough.
